Terms of Service

Last updated: 12 August 2026

These Terms of Service ("Terms") are a contract between you and Adam Meadows, a sole trader trading as Checkpoint64 ("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, 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.

Consumers and business users. In these Terms a consumer is an individual using the Service wholly or mainly outside any trade, business, craft, or profession. Anyone else — a company, someone using the Service for their own business, or someone acting on an organisation's behalf — is a business user.

The difference matters in Sections 12, 13, and 14. Those exclusions and limits apply in full to business users. If you are a consumer, you keep every right the law gives you, and nothing in these Terms takes those rights away, whatever else they appear to say.

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.

Features, pricing, storage quotas, and tier names may change over time. Section 11 explains when we may change the Service and what we will tell you first.

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 the Service for you. This licence exists so we can technically deliver the backup, restore, and sharing features you use — nothing else. We do not use Your Content to train machine-learning models, we do not sell or share it with advertisers, and we do not analyse its contents for product research. 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.

Keep your own copies. You agree to keep your own separate copies of any save files that matter to you, and not to rely on Checkpoint64 as your only copy. This is a genuine allocation of risk between us, not just advice: no backup service can promise a file will always be there, and the point of a second copy is that no single copy is trusted. Section 12 explains what this means if something goes wrong.

We do not read or monitor the contents of Your Content, with one automated exception: files uploaded into a team namespace are scanned for malware, because a team namespace hands one member's files to another member's PC. Files in your personal namespace are never scanned. No person reads your files either way. This is described in Section 2.7 of our Privacy Policy.

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.

  • One-off plans. The Paid plan, and every plan bought on Steam, is a one-time payment rather than a subscription — on Steam both Paid and Pro are DLC you buy once and keep. A one-off plan grants the rights described in that plan for as long as the Service remains commercially available to your account. It is not a promise that the Service itself will exist forever, and it does not entitle you to features later added to a different plan tier.
  • Subscription plans. Pro bought directly through Stripe is billed in advance on a recurring basis until you cancel. You can cancel at any time from your account, and cancellation takes effect at the end of the current billing period. Pro bought on Steam is a one-off DLC purchase and does not recur.
  • The 14-day cancellation right. If you are a consumer in the UK or EU and you buy directly through Stripe, you normally have 14 days to cancel a purchase of digital content and get your money back. You lose that right only where you expressly consented to us supplying the content immediately and acknowledged that doing so ends your right to cancel. It is never lost automatically, by default, or merely because you started using the Service. Where the right still applies, we will refund you.
  • Other refunds. Beyond your statutory rights we may offer goodwill refunds at our discretion, but we are not obliged to. Purchases made through Steam are refunded by Valve under the Steam Refund Policy, not by us — we cannot refund a Steam purchase even if we want to.
  • 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 parts of the Service, but only for a good reason — such as fixing a security problem, complying with the law, responding to a supplier or platform change, reflecting a change in our costs, or improving how the Service works. We will not make changes that materially reduce what a paid plan gives you without telling you first.

If a change materially and adversely affects a plan you have paid for, we will give you reasonable advance notice, and you may end that plan and ask us for a refund of any part you have paid for but not yet received. Purchases made through Steam are refunded by Valve under its own policy.

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 promise that the Service will remain available indefinitely. The Service is provided "as-is" and "as-available".

Checkpoint64 is an additional backup, not your only one. As agreed in Section 4, you keep your own copies of the save files that matter to you. Backups can fail — through a bug, an outage, an interrupted upload, a storage-provider incident, or your own device losing data before it ever syncs. Please do not let Checkpoint64 be the only thing standing between you and a lost run.

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

If you are a consumer, none of this removes your legal rights. We must supply a service with reasonable care and skill, and we do not exclude our liability for failing to do so. Nothing in this section applies to the extent it would exclude or restrict a right that the law does not permit us to exclude or restrict. If you are a business user, this section applies to you in full.

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,
  • any liability under the Consumer Rights Act 2015 that cannot be excluded or restricted — including our duty to supply a service with reasonable care and skill, 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 loss of profits, revenue, goodwill, business, or anticipated savings, 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 business user, the exclusions and the cap above apply to you in full, and we additionally exclude all liability for loss of or damage to data and save files.

If you are a consumer, we do not exclude liability for loss or damage that is a foreseeable result of us breaking these Terms or failing to use reasonable care and skill. Loss or damage is foreseeable if it was obvious that it would happen, or if both of us knew it might happen when you started using the Service. We are not liable for loss or damage that was not foreseeable, that was caused by events outside our reasonable control, or that resulted from you not keeping your own copies as agreed in Section 4. Nothing here affects your statutory rights.

14. Indemnity (business users only)

This section applies only if you are a business user. It does not apply to consumers — if you are a consumer, your responsibility to us is limited to ordinary damages for breach of these Terms under the general law, and you are not asked to indemnify anyone.

If you are a business user, you agree to indemnify and hold harmless Adam Meadows (trading as Checkpoint64) and anyone we engage to help operate the Service, 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 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.

Where we can reasonably do so, we will warn you first and give you a chance to put things right. We may act immediately and without notice where the breach is serious, where the law requires it, or where waiting would risk harm to the Service or to other users. If we discontinue the Service, or a part of it you have paid for, we will give you as much notice as we reasonably can.

On termination, your right to use the Service ends. Except where the law or a serious breach prevents it, we will give you a reasonable opportunity to export Your Content before it is removed, and will then delete it in accordance with our Privacy Policy. You can export your data at any time while your account is open, and we recommend doing so before you close it.

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.

19. Contact and complaints

Questions about these Terms? Email legal@checkpoint64.com.

If something has gone wrong, tell us first. Email support@checkpoint64.com and we will try to put it right. Most problems are resolved fastest this way, and we would much rather hear about one than not.

If we cannot resolve a complaint between us, you are free to take the matter to court as described in Section 17. We do not currently participate in an alternative dispute resolution (ADR) scheme and are not obliged to use one.

Checkpoint64 is operated by Adam Meadows, a sole trader established in the United Kingdom. It is not a registered company. Our postal address is available on request by email, including where you need it to serve notice.
