Terms of Service

Last updated: March 2026

Welcome to Spronta. These Terms of Service (“Terms”) govern your access to and use of the Spronta platform, APIs, SDKs, and related services (collectively, the “Service”) provided by Spronta Ltd (“Spronta”, “we”, “us”, or “our”).

By creating an account or using the Service, you agree to these Terms. If you are using the Service on behalf of an organisation, you represent that you have authority to bind that organisation, and “you” refers to that organisation.

What these Terms cover — a plain English summary

This table is a guide, not a legal summary. The full terms below govern your use of the Service.

1. The Service

Spronta provides image and media infrastructure including storage, transformation, optimisation, and delivery via a global CDN. We may update, expand, or modify the Service over time. We'll give you reasonable notice of any changes that materially affect your use.

2. Accounts

2.1 Registration

You must provide accurate information when creating an account. You are responsible for maintaining the security of your credentials and for all activity that occurs under your account. Notify us immediately at hello@spronta.com if you suspect unauthorised access.

2.2 Eligibility

You must be at least 18 years old to use the Service. By using the Service, you confirm that you meet this requirement.

2.3 One account per person

Free plan accounts are limited to one per individual or organisation. We reserve the right to close duplicate accounts.

3. Plans and Billing

3.1 Free plan

We offer a free tier with defined resource limits. The free tier may be used for commercial purposes. We may change free tier limits with 30 days' notice. We will not retroactively charge for usage incurred under a free plan.

3.2 Paid plans

Paid plans are billed monthly or annually in advance. All prices are listed on our pricing page and exclude VAT where applicable. VAT will be added at checkout for customers in applicable jurisdictions.

3.3 Overages

If you exceed your plan limits, we will notify you. We will not suspend your account or charge overage fees without your prior consent. You may choose to upgrade your plan or reduce usage. We will never suspend your account without warning for exceeding limits.

3.4 Annual plans

Annual plans are paid upfront and are non-refundable after 14 days, except where required by law.

3.5 Cancellation

You may cancel your subscription at any time from your account dashboard. Your plan will remain active until the end of the current billing period. We do not offer pro-rata refunds for unused time on monthly plans.

3.6 Refunds

If you are unsatisfied within your first 14 days on a paid plan and have not exceeded 10GB of storage or 50,000 API calls during that period, contact us and we will issue a full refund, no questions asked. We reserve the right to decline refund requests where usage indicates the Service has been used in a manner inconsistent with a genuine evaluation.

3.7 Late payment

If payment fails, we will retry and notify you. Accounts with failed payments may have upload and delivery functionality restricted after 14 days of non-payment. We will not delete your data for at least 30 days following account suspension.

4. Acceptable Use

You may use the Service to store, transform, optimise, and deliver media assets for any lawful purpose, including commercial use, on any plan tier.

4.2 Prohibited content

The full list of prohibited content and behaviours is set out in our Acceptable Use Policy, which forms part of these Terms. In summary, you must not upload, store, or deliver content that:

• Is illegal under applicable law
• Depicts or facilitates child sexual abuse or exploitation
• Promotes violence, terrorism, or hate speech targeting protected characteristics
• Infringes the intellectual property rights of any third party
• Contains malware, ransomware, or other malicious code

We may update the Acceptable Use Policy from time to time to address new abuse patterns or legal requirements. We will notify you of material changes.

• Use the Service to conduct denial-of-service attacks or other malicious activity

• Use automated means to create multiple free accounts
• Use the Service in a way that causes disproportionate load or disrupts other customers

4.4 Enforcement

We may investigate suspected violations and suspend or terminate accounts that breach these Terms or our Acceptable Use Policy. Where practical, we will give you notice and an opportunity to remedy the issue before taking action. For serious violations (particularly prohibited content), we may act immediately.

5. Your Content

5.1 Ownership

You retain full ownership of all content you upload to the Service (“Your Content”). These Terms do not transfer any intellectual property rights from you to us.

5.2 Licence to operate the Service

By uploading Your Content, you grant us a limited, non-exclusive, royalty-free licence to store, process, transform, cache, and deliver Your Content solely as necessary to provide the Service to you. This licence ends when you delete the content or close your account.

5.3 Your responsibility

You are responsible for ensuring that Your Content complies with these Terms, our Acceptable Use Policy, and applicable law. We are not responsible for reviewing Your Content and do not endorse it.

5.4 Deletion

When you delete content or close your account, we will remove Your Content from our systems within 30 days. Copies may persist in backups for up to 90 days, after which they will be permanently deleted.

6. Data Protection and Privacy

6.1 Privacy Policy

Our Privacy Policy explains how we collect, use, and protect personal data. By using the Service, you agree to our Privacy Policy.

6.2 GDPR

If you are based in the UK or European Economic Area, or if you process personal data of UK or EEA residents using the Service, our Data Processing Agreement (“DPA”) applies. You can request a copy of our DPA at hello@spronta.com.

6.3 Data residency

Your assets are stored using infrastructure provided by Cloudflare, Inc. You can request information about storage regions for compliance purposes.

6.4 Your obligations

If Your Content includes personal data relating to third parties (such as user-uploaded photos), you are responsible for having a lawful basis to process and store that data, and for complying with applicable data protection law.

7. Uptime and Availability

7.1 Availability

We target 99.9% uptime for the delivery and API infrastructure and operate on a commercially reasonable basis to achieve this. We do not offer contractual SLAs.

7.2 Scheduled maintenance

We will provide advance notice of scheduled maintenance that may affect availability. We aim to schedule maintenance during low-traffic periods.

7.3 No guarantees

The Service is provided on a commercially reasonable basis. We do not guarantee uninterrupted or error-free service.

8. Intellectual Property

8.1 Spronta IP

The Service, including its software, design, documentation, trademarks, and brand assets, is owned by Spronta and protected by intellectual property law. Nothing in these Terms grants you any rights in Spronta's intellectual property except as expressly stated.

8.2 Feedback

If you provide us with feedback, suggestions, or ideas about the Service, you grant us a perpetual, irrevocable, royalty-free licence to use that feedback for any purpose without obligation to you.

9. API and SDK Usage

9.1 API access

Access to the Spronta API is granted via API keys issued to your account. You are responsible for keeping your API keys confidential and for all usage that occurs under your keys. You must not share API keys publicly, embed them in client-side code, or commit them to public repositories.

9.2 Compromised credentials

If you believe an API key has been compromised, you must rotate it immediately via your account dashboard and notify us at hello@spronta.com. We are not liable for usage or charges incurred as a result of unauthorised use of your credentials prior to notification.

9.3 Rate limits

The Service operates rate limits per plan tier, as documented. You must not attempt to circumvent rate limits. If you have a legitimate need for higher limits, contact us to discuss an appropriate plan or custom arrangement.

9.4 SDK licence

We may provide open-source SDKs and client libraries under separate licence terms stated in the relevant repository. Those licence terms govern your use of the SDK code itself. These Terms govern your use of the Service the SDKs connect to.

9.5 No competitive use or public benchmarking

You must not use API access to the Service to build, train, benchmark, or improve a product or service that directly competes with Spronta. This includes using Spronta's transformation outputs, metadata, or delivery infrastructure to replicate or reverse-engineer our core functionality for a competing product. You must not publish or distribute performance benchmarks or comparative analyses of the Service without our prior written consent.

10. Beta and Early Access Features

10.1 Beta features

We may make features available as “beta”, “preview”, “experimental”, or similarly labelled functionality. Beta features are provided for evaluation purposes and are not subject to the same availability, reliability, or support commitments as generally available features.

10.2 No warranties on beta features

Beta features are provided without warranty of any kind. We are not liable for any data loss, service disruption, or other harm arising from your use of beta features. You should not use beta features in production environments where reliability is critical unless you have accepted that risk.

10.3 Changes and withdrawal

We may modify, suspend, or permanently withdraw any beta feature at any time without notice and without liability. Graduation of a beta feature to general availability, or its withdrawal, does not entitle you to any refund or compensation.

10.4 Feedback on beta features

We may ask for feedback on beta features. Any feedback you provide is subject to the feedback licence in §8.2.

11. AI-Powered Features

11.1 What this covers

Spronta offers optional AI-powered features including but not limited to: automatic image tagging, alt text generation, content-aware cropping, background removal, generative image creation, and visual search. These features are powered by third-party AI model providers and our own processing pipelines.

11.2 Nature of AI outputs

AI-generated and AI-assisted outputs (such as auto-generated alt text, tags, or generated images) are provided as-is. They may be inaccurate, incomplete, or unsuitable for your purposes. You are responsible for reviewing and validating any AI outputs before use, particularly in contexts where accuracy is important (such as accessibility descriptions or legal compliance).

11.3 AI-generated content ownership

Where you use Spronta's generative features to create images, you own the output subject to the licences of the underlying AI models used. We will make the relevant model terms available in our documentation. You represent that your use of AI-generated content complies with applicable law, including any requirements around disclosure of AI-generated material.

11.4 Content moderation

AI generation features include automated content moderation to prevent generation of prohibited content. This moderation is not perfect. If content is incorrectly blocked, you may contact us to request a review. Repeated attempts to circumvent moderation may result in account suspension.

11.5 Third-party AI providers

Some AI features are powered by third-party providers. By using these features, your prompts and any relevant asset metadata may be transmitted to those providers subject to their terms. We will identify which providers are used in our documentation.

12. Copyright and DMCA

12.1 Respect for intellectual property

Spronta respects intellectual property rights and expects users to do the same. You must not upload, store, or deliver content that infringes the copyright, trademark, or other intellectual property rights of any third party.

12.2 Copyright infringement notices

If you believe that content stored or delivered through the Service infringes your copyright, you may submit a notice to our designated agent:

Your notice must include:

• Identification of the copyrighted work you claim has been infringed
• Identification of the allegedly infringing material and its location on our Service (e.g. the URL)

• A statement, under penalty of perjury, that the information in your notice is accurate and that you are the copyright owner or authorised to act on their behalf

We will act on valid notices promptly, which may include removing or disabling access to the identified content.

If you believe content was removed in error, you may submit a counter-notice to hello@spronta.com containing:

• Identification of the removed content and its former location
• A statement under penalty of perjury that you have a good faith belief the content was removed as a result of mistake or misidentification
• Your contact information and consent to jurisdiction of the courts of England and Wales
• Your physical or electronic signature

Upon receipt of a valid counter-notice, we may restore the content after notifying the original complainant.

12.4 Repeat infringers

We will terminate accounts of users who are found to be repeat infringers of third-party intellectual property rights.

13. Publicity and Customer References

13.1 Our use of your name and logo

By using the Service, you grant us permission to identify you as a Spronta customer. This includes using your company name and logo in our marketing materials, website, case studies, investor materials, and press releases.

We will always use your brand assets in accordance with any brand guidelines you make publicly available or share with us. If you provide us with brand guidelines, we will follow them. If no guidelines are provided, we will use your name and logo in good faith in a manner consistent with how you present your own brand.

13.2 Opting out

You may opt out of this permission at any time by contacting us at hello@spronta.com. We will remove references to your brand from new materials promptly following your request. We are not required to recall or destroy materials already in circulation, such as printed assets or published case studies, but will not use your brand in new materials after receiving your opt-out.

13.3 No endorsement implied

Our use of your name or logo does not imply your endorsement of Spronta. We will not represent that you endorse us without your explicit written consent.

13.4 Case studies

If we wish to publish a detailed case study featuring your company, we will seek your prior written approval for that specific content before publication.

14. Confidentiality

Each party may receive confidential information from the other. Both parties agree to keep such information confidential and not to disclose it to third parties without prior written consent, except as required by law. This obligation does not apply to information that is publicly available, already known, or independently developed.

15. Security

15.1 Our security obligations

We implement and maintain reasonable technical and organisational security measures appropriate to the nature of the Service. We will notify you promptly if we become aware of a security breach that affects Your Content.

15.2 Responsible vulnerability disclosure

If you discover a potential security vulnerability in the Service, we ask that you report it to us responsibly by emailing hello@spronta.com before disclosing it publicly. We commit to acknowledging your report within 5 business days and working with you in good faith to understand and resolve the issue before any public disclosure. We will not take legal action against researchers who act in good faith in accordance with this policy.

15.3 Your security obligations

You are responsible for implementing appropriate security measures to protect your API keys, account credentials, and any content you transmit through the Service.

16. Disclaimers and Statutory Rights

TO THE FULLEST EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.

WE DO NOT WARRANT THAT THE SERVICE WILL MEET YOUR REQUIREMENTS, THAT RESULTS OBTAINED THROUGH THE SERVICE WILL BE ACCURATE, OR THAT ANY ERRORS WILL BE CORRECTED.

Nothing in these Terms is intended to exclude or restrict any rights you have under the Unfair Contract Terms Act 1977, the Consumer Rights Act 2015, or any other applicable UK consumer protection legislation that cannot lawfully be excluded. If you are a consumer, your statutory rights are not affected by these Terms.

17. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW:

SPRONTA'S TOTAL AGGREGATE LIABILITY TO YOU ARISING OUT OF OR IN CONNECTION WITH THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE FEES PAID BY YOU TO SPRONTA IN THE THREE MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

SPRONTA SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, LOSS OF DATA, LOSS OF GOODWILL, OR BUSINESS INTERRUPTION, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Nothing in these Terms limits liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation, or any other liability that cannot be limited under applicable law.

18. Indemnification

YOU AGREE TO INDEMNIFY AND HOLD HARMLESS SPRONTA, ITS OFFICERS, EMPLOYEES, AND CONTRACTORS FROM ANY CLAIMS, DAMAGES, LOSSES, OR EXPENSES (INCLUDING REASONABLE LEGAL FEES) ARISING FROM: (A) YOUR USE OF THE SERVICE IN BREACH OF THESE TERMS; (B) YOUR CONTENT; OR (C) YOUR VIOLATION OF ANY THIRD-PARTY RIGHTS OR APPLICABLE LAW.

19. Term and Termination

19.2 Termination by you

You may close your account at any time via your account settings or by contacting us.

Upon termination, your right to access the Service ceases. We will retain Your Content for 30 days following termination to allow you to export it, after which it will be deleted.

19.5 Survival

Clauses relating to intellectual property, confidentiality, disclaimers, limitation of liability, indemnification, and governing law survive termination.

20. Changes to These Terms

We may update these Terms from time to time. We will notify you of material changes by email or via an in-app notification at least 14 days before they take effect. Your continued use of the Service after changes take effect constitutes acceptance of the updated Terms. If you do not agree to updated Terms, you may close your account before the changes take effect.

21. Formation of Contract and Electronic Acceptance

21.1 How the contract is formed

These Terms constitute a legally binding contract between you and Spronta. The contract is formed when you: (a) click a button or checkbox indicating your acceptance of these Terms; (b) create an account; or (c) otherwise use the Service, whichever occurs first.

21.2 Electronic acceptance

You acknowledge that your electronic acceptance of these Terms — whether by clicking “I agree”, “Sign up”, or similar — constitutes a valid and binding agreement under English contract law, and is as legally effective as a handwritten signature.

21.3 Capacity

By accepting these Terms, you confirm that you have legal capacity to enter into a binding contract and, if acting on behalf of an organisation, that you have authority to bind that organisation.

22. Notices

22.1 Notices to you

We will send notices to you at the email address associated with your account. Notices are deemed received 24 hours after sending, provided we do not receive a delivery failure notification. It is your responsibility to keep your account email address current.

22.2 Notices to us

All notices to Spronta, including legal notices, must be sent by email to hello@spronta.com. Legal notices are deemed received on the next business day following confirmed delivery.

22.3 Language

All notices and communications under these Terms shall be in English.

23. Governing Law and Dispute Resolution

23.1 Governing law

These Terms and any dispute or claim arising out of or in connection with them (including non-contractual disputes or claims) are governed by and construed in accordance with the laws of England and Wales.

23.2 Informal resolution first

Before initiating any formal dispute process, both parties agree to attempt to resolve the dispute informally. The party raising the dispute must send a written notice to the other describing the nature of the dispute and the remedy sought. Both parties agree to negotiate in good faith for at least 30 days from receipt of that notice before proceeding to arbitration. This requirement does not apply where a party seeks urgent interim or injunctive relief.

23.3 Binding arbitration

If informal resolution fails, any dispute, controversy, or claim arising out of or in connection with these Terms, or the breach, termination, or invalidity thereof, shall be finally resolved by binding arbitration under the rules of the London Court of International Arbitration (LCIA), which rules are incorporated by reference into this clause.

• Seat of arbitration: London, England
• Language: English
• Number of arbitrators: One (1), unless the amount in dispute exceeds £250,000, in which case either party may request a panel of three (3)
• Appointing authority: The LCIA

The arbitrator's award shall be final and binding on both parties and may be enforced in any court of competent jurisdiction. The parties agree to keep arbitration proceedings and any award confidential, except as required by law or to enforce an award.

23.4 Exceptions to arbitration

Notwithstanding the above, either party may seek urgent interim or injunctive relief from the courts of England and Wales without first exhausting the informal resolution process or arbitration procedure. This does not waive either party's right to arbitrate the underlying dispute.

23.5 Consumer carve-out

If you are a consumer (an individual using the Service for personal, non-commercial purposes), you are not bound by the arbitration clause and retain the right to bring proceedings in the courts of England and Wales. Nothing in these Terms affects your statutory rights as a consumer under applicable UK law, including the Consumer Rights Act 2015.

23.6 No class proceedings

All disputes must be brought on an individual basis. Neither party may bring or participate in any class, collective, or representative action or arbitration arising out of or relating to these Terms or the Service. This clause does not prevent either party from bringing a claim in their individual capacity.

23.7 US customers — notice and right to opt out of arbitration

If you are located in the United States, you have the right to opt out of the binding arbitration clause in §23.3 and the no class proceedings clause in §23.6 by sending written notice to hello@spronta.com within 30 days of first accepting these Terms. Your notice must include your full name, account email address, and a clear statement that you are opting out of arbitration. If you opt out, disputes will be resolved in the courts of England and Wales in accordance with §23.1, and both parties retain all other rights and obligations under these Terms. Opting out will not affect your ability to use the Service.

If you do not opt out within 30 days, you will be deemed to have accepted the arbitration clause. We will maintain a record of opt-out notices received.

24. Export Controls

24.1 Compliance with export laws

The Service may be subject to export control laws and regulations, including but not limited to the United States Export Administration Regulations (EAR), the Office of Foreign Assets Control (OFAC) sanctions programmes, and equivalent laws in the United Kingdom and European Union. You agree to comply with all applicable export control and sanctions laws in connection with your use of the Service.

24.2 Your representations

By using the Service, you represent and warrant that:

• You are not located in, and are not a national or resident of, any country subject to a comprehensive US, UK, or EU trade embargo, including Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, and Luhansk regions of Ukraine
• You are not listed on any US government restricted party list, including the OFAC Specially Designated Nationals list, the US Commerce Department Denied Persons List, or the US State Department Debarred Parties list
• You will not use the Service to transmit, transfer, or otherwise make available any content or technology in violation of applicable export control or sanctions laws

24.3 Our right to restrict access

We reserve the right to restrict or terminate access to the Service for any user or region where we determine, in our reasonable judgment, that continued access would violate applicable export control or sanctions laws. We will not be liable for any loss or damage arising from such restrictions.

24.4 No facilitation

You must not use the Service to facilitate transactions or activities that would violate applicable export control or sanctions laws, including storing or delivering content on behalf of sanctioned parties.

25. General

25.1 Entire agreement

These Terms, together with our Privacy Policy, Acceptable Use Policy, and any applicable DPA, constitute the entire agreement between you and Spronta regarding the Service.

25.2 Severability

If any provision of these Terms is found to be unenforceable, it will be modified to the minimum extent necessary to make it enforceable. The remaining provisions continue in full force.

25.3 No waiver

Our failure to enforce any provision of these Terms does not constitute a waiver of our right to enforce it in the future.

25.4 Assignment

You may not assign your rights or obligations under these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of substantially all of our assets.

25.5 Force majeure

Neither party shall be liable for delays or failures caused by circumstances beyond their reasonable control, including natural disasters, government actions, or infrastructure failures.
