In short
Photos and PDFs of your notes are read on your iPhone and never leave it. To draw the map, the summary and the study questions with artificial intelligence, Trazo sends only the TEXT it already read to our server and, from there, to Claude, Anthropic’s model. We do not keep that text or the model’s answer.
What leaves your phone, and why
The text of the note, how many pages it has and its language: to generate the map, summary and questions. It is processed on the spot and our server does not keep it.
An anonymous user identifier (no name, no email, no account) and a random device identifier: to count how many AI maps you used (the free one, the Premium allowance and the daily cap) and so that reinstalling the app does not grant another free one. Next to them we keep only usage data: date, number of pages and characters, model used, tokens, cost and whether it worked. Never the content.
If there is no connection or the service does not answer, the map is drawn on your phone as always, and the app tells you so.
Anthropic (Claude)
Anthropic processes the text as our provider, under its commercial terms: it does not use it to train its models. It may retain it for a limited time (up to 30 days) for safety and abuse prevention, and then deletes it.
What stays on your phone
Maps, summaries and questions are stored only on your iPhone. They are gone when you delete the map or the app. Trazo does not keep the images of your notes.
Your material is never used to train any model, ours or anyone else’s.
Anonymous measurement
To improve the app we measure usage steps (for example, that a map was requested or that the plans screen was opened) with a random install identifier. It never includes the text of your notes or personal data.
Minors
Trazo is made for students, including minors. That is why there are no ads, no profiling, no selling or sharing of data, and no personal data is required to use the app.
Purchases
If you subscribe, Apple processes the purchase. We use RevenueCat to know whether your subscription is active; that means an anonymous purchase identifier, with no name or email. Apple reports sales to us in aggregate.
Your rights
Your notes do not stay on our server. The anonymous usage records (date, pages, cost) do not identify you; if you want us to delete the ones from your device, write to us. Deleting a map removes it from your phone; uninstalling the app removes everything it stores.
