Kartesio

Terms of Service

Last updated: 8 August 2026

1. What Kartesio is

Kartesio reads a photographed or typed exercise, solves it step by step, draws the relevant graph, and can check work you have already done. It is a study tool, meant to help you understand a method — not to replace your own reasoning.

2. Accuracy

Explanations are produced by an artificial intelligence model and verified, where possible, by a deterministic computer algebra system. Results marked as automatically verified have been checked by that system. Everything else should be read critically: mistakes are possible, and you should not submit an answer you do not understand.

We provide the service as it is, without warranty that every result is correct or fit for a particular purpose. You remain responsible for the use you make of it, including in school assessments, where your institution's rules apply.

3. Scans, ads and credits

Each scan consumes one credit. New credits are earned by watching a rewarded advertisement, up to a daily limit. Credits have no monetary value, cannot be purchased, transferred or refunded, and reset each day.

Watching an advertisement is always your choice. If an ad fails to load or you close it early, no credit is granted.

4. Acceptable use

You agree not to:

We may suspend access where these terms are breached.

5. Intellectual property

The app, its name and its design belong to the developer. The exercises you photograph remain yours and are not claimed by us. Mathematical results are facts and belong to no one.

6. Availability

Kartesio depends on third-party services and may be unavailable, interrupted or discontinued. We do not guarantee continuity and are not liable for damages arising from unavailability.

7. Liability

To the extent permitted by law, our liability is limited to what cannot be excluded under applicable consumer legislation. Nothing here limits rights that the law grants you and that cannot be waived.

8. Changes

These terms may be updated. Continuing to use the app after a change means you accept the new version.

9. Governing law

These terms are governed by Italian law. If you are a consumer, you retain the protections of the mandatory rules of your country of residence.
