AniNotes is a note-taking app for students. We designed it to keep your data on your device.
What we collect
Nothing. AniNotes has no user accounts, does not track you, and contains no analytics or advertising SDKs. Your notes, drawings, and notebooks are stored only on your device (and in your own iCloud/device backups if you have those enabled).
Network use
AniNotes works fully offline. The only time it makes a network request is when you ask it to build a molecule it doesn't have built in: it sends the molecule name or chemical formula you typed (for example "caffeine" or "H2O2") to the U.S. National Institutes of Health PubChem service to fetch that molecule's structure. This request contains no personal information and is not linked to you or your device. Once fetched, the molecule is saved inside your note and works offline thereafter. PubChem is operated by the NIH; see their policies.
Handwriting recognition
Recognizing your handwriting (to graph an equation, build a molecule, or clean up text) happens entirely on your device — using a recognition model bundled inside the app, with Apple's on-device Vision framework as a fallback. Your ink is never sent anywhere for recognition.
Purchases
AniNotes offers a one-time in-app purchase ("AniNotes Pro"). Payments are handled entirely by Apple through the App Store — we never see or store your payment information.
Children's privacy
Because AniNotes collects no personal data and has no accounts, it is safe for use by students of all ages. We do not knowingly collect any information from anyone.
Changes
If this policy changes, we'll update this page and the "last updated" date.
