Terms of Service

Last updated: 19 May 2026

These Terms of Service ("Terms") are a contract between you and [LEGAL ENTITY] ("Checkpoint64", "we", "us", "our"). They govern your use of:

  • the website at checkpoint64.com and any subdomains we operate (the "Site"),
  • the Checkpoint64 desktop application for Windows, macOS, and Linux (the "App"), and
  • the Checkpoint64 cloud backup service, account system, and APIs (together the "Service").

By using the Site, joining the launch list, downloading the App, or creating an account, you agree to these Terms. If you do not agree, do not use the Service.

1. Who can use the Service

You must be at least 16 years old to create an account or otherwise use the Service. If you are using the Service on behalf of an organisation, you confirm that you have authority to bind that organisation to these Terms.

You must not use the Service if you are prohibited from doing so under the laws of your country or any country we operate in.

2. The Service today

Checkpoint64 is a save-file backup tool for PC games. It takes snapshots of folders you point it at, uploads only the files that changed to cloud storage, and lets you roll back to earlier versions. It also lets small groups share a single live save through co-operative locks and a shared activity log.

The Service is in pre-launch development. Today the Site is primarily a marketing page and waitlist signup. The App and cloud service are being tested privately and will be made generally available at a later date. Features, pricing, storage quotas, and tier names may change before launch, and we may add, remove, or alter functionality at any time.

3. Accounts

To use most of the Service you will need an account. You can create one with an email address and password, or by signing in with Google or GitHub via OAuth. Some activation flows go through Steam, in which case your account is linked to a Steam ID.

You agree to:

  • provide accurate information when registering and keep it up to date,
  • keep your password and any access tokens confidential,
  • not share your account with anyone else, and
  • notify us promptly at security@checkpoint64.com if you believe your account has been compromised.

You are responsible for everything that happens under your account, including any uploads made by people you grant access to a team you control.

4. Your saves and your content

The save files, folders, manifests, names, screenshots, comments, and any other content you upload through the Service ("Your Content") remain yours. You retain all rights you had in Your Content before uploading it.

You grant Checkpoint64 a worldwide, non-exclusive, royalty-free licence to host, store, copy, transmit, deduplicate, encrypt, and serve Your Content back to you and to people you explicitly share it with, solely for the purpose of operating and improving the Service. This licence ends when you delete Your Content from the Service, except to the extent we need to retain copies for backup, security, or legal-compliance reasons (see Section 13 of our Privacy Policy).

You are solely responsible for Your Content. You confirm that you have the right to upload everything you upload, that it does not infringe anyone else's rights, and that it does not violate the Acceptable Use rules below or the terms of the games it came from.

We do not actively monitor Your Content, but we may remove or restrict access to anything that violates these Terms, the rights of others, or applicable law.

5. Acceptable use

You agree not to use the Service to:

  • upload anything illegal, malicious, infringing, or that you don't have the right to upload,
  • upload save files or other content from games whose terms of service prohibit cloud sync or re-distribution of save data,
  • circumvent paywalls, anti-cheat systems, DRM, licensing, or version controls in any game,
  • distribute malware, viruses, exploits, or save files crafted to corrupt or exploit other users' systems,
  • use the Service to attack or interfere with anyone else's systems, including the Service itself,
  • attempt to break, probe, or reverse-engineer the Service beyond what is permitted by applicable law,
  • scrape, mirror, or republish the Service or its data without our written permission,
  • use the Service to store anything that has nothing to do with game saves, such as bulk media, backups of unrelated personal files, or other people's data,
  • impersonate anyone, or misrepresent your affiliation with any person, team, or game studio,
  • abuse free-tier limits by creating multiple accounts to multiply the free quota, or
  • resell, sublicense, or commercialise the Service without our written agreement.

We may suspend or terminate access for any account we reasonably believe is engaged in any of the above, with or without notice.

6. Storage quotas and fair use

Each plan has a storage quota and other usage limits. Quotas are enforced server-side when you upload, and uploads that would exceed your quota will be rejected.

We may apply reasonable fair-use limits to API throughput, request rate, the number of versions kept per save, retention duration, and the number of teams or seats per account, to keep the Service stable for everyone. Where we publish guaranteed minimums for a paid plan, we will honour those minimums; everything else may change with notice.

7. Beta, preview, and "coming soon" features

Some features are explicitly labelled as beta, preview, early-access, or "coming soon". These are provided as-is, without any warranty or guarantee that they will become a generally available part of the Service. They may break, change shape, or disappear at any time, and they may have stricter rate or storage limits than production features.

8. Payment, plans, and refunds

Some plans require payment. Payments are processed by Stripe, or, for accounts activated through Steam, by Valve / Steam. When you pay through Stripe, you accept Stripe's own terms; when you pay through Steam, you accept Valve's Subscriber Agreement and Steam Refund Policy. We do not see or store your full card details.

  • Lifetime plans. A "lifetime" plan is a one-time payment that grants the rights described in the plan for as long as the Service remains commercially available to that account. It is not a perpetual guarantee that the Service itself will exist forever, and it does not entitle you to features added to a different plan tier later.
  • Subscription plans (e.g. Pro). Billed in advance on a recurring basis until you cancel. You can cancel at any time from your account; cancellation takes effect at the end of the current billing period.
  • Refunds. For direct purchases via Stripe in the UK/EU, you have the statutory right to cancel within 14 days of purchase, except where you have started using the Service and expressly consented to that right being waived, which is the default for digital content delivered immediately. Beyond statutory rights, we may at our discretion offer goodwill refunds, but we are not obliged to. Refunds for purchases made through Steam are handled by Steam under its own refund policy.
  • Price changes. We may change prices for new purchases at any time. For active subscriptions, we will give you at least 30 days' notice before any price change takes effect; you can cancel before the new price applies.
  • Taxes. Prices may be displayed exclusive of VAT or other applicable taxes. The amount actually charged will include any tax we are required to collect.

9. Third-party services and game studios

Checkpoint64 backs up files written to disk by third-party games. We are not affiliated with, endorsed by, or sponsored by any game studio, publisher, console manufacturer, or platform mentioned on the Site or supported by the App. Game and brand names are the property of their respective owners.

You are responsible for complying with the terms of service of the games whose saves you back up, and for the terms of any third-party platform you use to sign in (Google, GitHub, Steam) or pay (Stripe, Steam).

10. Software licence

The App is licensed, not sold. Subject to your compliance with these Terms and any active subscription, we grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the App on devices you own or control, solely to access the Service.

You may not copy, modify, distribute, sell, lease, sublicense, or reverse-engineer the App, except to the extent applicable law expressly permits despite this restriction (for example, to achieve interoperability).

The App may include open-source components governed by their own licences. Those licences are listed inside the App and continue to apply.

11. Updates

The App may download and install updates automatically, including security and bug-fix updates. You consent to these updates as a condition of using the App. We may also change, suspend, or discontinue any part of the Service at any time, with or without notice, although for paid plans we will give reasonable notice of material changes.

12. Service availability, "as-is", and warranty disclaimer

We work hard to keep the Service running, but we do not guarantee uninterrupted, error-free, or perfectly secure operation, and we do not guarantee that any specific save will always be recoverable. The Service is provided "as-is" and "as-available".

To the maximum extent permitted by law, we disclaim all warranties, whether express, implied, statutory, or otherwise, including any warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, and any warranty arising from a course of dealing or trade usage.

Always keep your own local copies of important save files. Treat Checkpoint64 as an additional backup, not your only one.

13. Limitation of liability

Nothing in these Terms limits or excludes our liability for:

  • death or personal injury caused by our negligence,
  • fraud or fraudulent misrepresentation, or
  • any other liability that cannot be limited or excluded under applicable law.

Subject to that, and to the maximum extent permitted by law:

  • we will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, goodwill, data, or save files, even if we have been advised of the possibility of such damages; and
  • our total aggregate liability arising out of or relating to the Service or these Terms, however caused, will not exceed the greater of (a) the amount you have paid us in the 12 months immediately before the event giving rise to the liability, or (b) £50.

If you are a consumer in the UK or EU, this section does not affect any non-waivable statutory rights you have.

14. Indemnity

You agree to indemnify and hold harmless Checkpoint64 and its officers, employees, and contractors from any claims, losses, damages, costs, and expenses (including reasonable legal fees) arising out of or relating to:

  • Your Content,
  • your use of the Service in breach of these Terms or applicable law, or
  • your violation of any third party's rights.

15. Termination

You may stop using the Service and close your account at any time from the account settings, or by emailing support@checkpoint64.com.

We may suspend or terminate your access to all or part of the Service, with or without notice, if:

  • you breach these Terms in a way that is material or repeated,
  • we are required to do so by law, by a court order, or by a payments or platform partner (e.g. Stripe, Steam),
  • we reasonably believe doing so is necessary to protect the Service, our users, or third parties, or
  • we discontinue the Service or the relevant part of it.

On termination, your right to use the Service ends immediately. We will make Your Content available for export for a reasonable period where practical, and will delete it in accordance with our Privacy Policy after that period.

Sections that by their nature should survive (including ownership of Your Content, payment obligations, disclaimers, limitation of liability, indemnity, and dispute resolution) will continue to apply after termination.

16. Changes to these Terms

We may update these Terms from time to time. When we do, we will revise the "Last updated" date at the top of this page. If the changes are material — for example, changes to fees, dispute resolution, or what we may do with Your Content — we will give you reasonable advance notice by email or in-app notification before they take effect.

Continued use of the Service after the changes take effect means you accept the revised Terms. If you do not accept them, you should stop using the Service and may close your account.

17. Governing law and disputes

These Terms and any dispute or claim arising out of or in connection with them, the Service, or their subject matter (including non-contractual disputes), are governed by the laws of England and Wales.

The courts of England and Wales will have exclusive jurisdiction over any such dispute, except that if you are a consumer resident in the UK or EU, you may also bring proceedings in the courts of the country where you live, and you retain the benefit of any mandatory consumer-protection rules of that country.

Nothing in this section prevents either party from seeking urgent interim or injunctive relief in any competent court.

18. Miscellaneous

  • Entire agreement. These Terms, together with the Privacy Policy and any plan-specific terms presented to you at purchase, are the entire agreement between you and us about the Service.
  • No waiver. If we don't enforce a right, that doesn't waive it.
  • Severability. If any part of these Terms is held unenforceable, the rest will continue in force.
  • Assignment. You may not assign or transfer your rights under these Terms without our written consent. We may assign these Terms in connection with a merger, acquisition, restructuring, or sale of assets.
  • Notices. We may give notices by email to the address on your account, or by posting them on the Site or inside the App.
  • No agency. Nothing here creates a partnership, joint venture, employment, or agency relationship between you and us.
