Terms of use

Last updated: 2026-07-07

These terms govern your use of Inkproof. By creating an account you accept them. Swiss law applies; place of jurisdiction is Zürich, Switzerland.

The service

Inkproof stores the course materials and work attempts you upload, produces machine transcripts, typeset feedback on your own work, study suggestions, and practice quizzes. Feedback, suggestions, and quiz gradings are generated by AI models: they can be wrong. They are a study aid, not a grade, a guarantee of exam results, or professional advice.

Your content and your warranty

You keep all rights to what you upload. You grant us the limited licence needed to store, process, and display it back to you — nothing more.

Upload warranty: by uploading a file you warrant that you are legally permitted to store and process it for personal study — for example your own notes and solutions, or lecture material your institution permits you to keep personal copies of.

No-textbook rule: commercial textbooks, solution manuals, and other material sold under licences that forbid copying may not be uploaded. We run automated heuristics against such uploads and block them; deliberately circumventing these checks is a violation of these terms.

Notice and takedown

Rights holders can report allegedly infringing content to legal@inkproof.io. We remove reported content promptly while we review the notice, and inform the uploader. Counter-notices go to the same address.

Repeat infringers — accounts that repeatedly upload infringing material — will be terminated.

Acceptable use

No attempts to disrupt the service, probe other users' data, resell access, or use the service for anything other than personal study. Accounts are personal and non-transferable.

Credentials and connected tools. WebDAV credentials and MCP access tokens are bearer secrets: anything done with them counts as done by you, so keep them confidential and revoke them in Settings if in doubt. They may only be used to access your own account.

Your own AI provider key. If you add your own Anthropic or OpenAI API key, calls made with it are billed by that provider to you under your agreement with them; set your own spending limits there. We may reject or disable a key that stops working. Removing the key returns your account to the plan's normal usage caps.

Referrals. Referral rewards (extra access time for both sides) apply once per referred person and only for genuine new users; self-referral or coordinated abuse voids the rewards.

Plans, payment, refunds

Prices are shown at checkout in CHF. The Exam Pass is a one-time purchase valid for 4 months; the monthly plan renews until cancelled (cancellable anytime via the customer portal, effective at period end). Statutory withdrawal rights remain unaffected.

Termination

You can delete your account at any time from Settings (see the privacy policy for what happens to your data). We may suspend or terminate accounts that violate these terms; where reasonable we warn first.

Liability

To the extent permitted by law, our liability is limited to intent and gross negligence; for slight negligence we are liable only up to the fees you paid us in the 12 months before the event. We are not liable for exam outcomes.

Changes

We may amend these terms with 14 days' notice by email. If you do not agree, you may delete your account before the change takes effect.
