Privacy & Support

Last updated: November 9, 2026

In short

Notzz is a personal notes app. What you write is stored only to be shown back to you. No ads, no tracking, no analytics; your data is never sold or shared with anyone for advertising.

What we store

  • Your account: your username, language preference and an irreversible hash of your password (the password itself is never stored).
  • The content you enter: notes, images you add to notes, to-dos, reminders, calendar events and your class schedule.
  • If you sign in with Google or Apple: the account ID and e-mail address the provider gives us (with Apple, possibly a private relay address). With Apple we also keep a token Apple issues, used only to revoke the Apple sign-in when you delete your account. We never see your Google or Apple password.
  • If you connect Google Calendar in Settings: the access tokens Google issues for syncing, and the synced events.
  • If you create an AI connection: the secret address of that connection.
  • Cookies to keep you signed in and remember your language. No other cookies or tracking technologies are used.

Where your data lives

The app runs on Vercel; the database is Neon (PostgreSQL) and images are stored on Vercel Blob. All connections are encrypted (HTTPS). Each account's data is isolated; no user can see another user's data.

What is shared with third parties

  • Google Gemini (AI): when you use automatic categorization (if turned on) or schedule reading, the relevant text or image is sent to Google for processing. These run only when you use them.
  • AI assistants you connect: if you create an address under Settings → AI Connection and give it to an assistant such as Claude or ChatGPT, that assistant can read your notes, to-dos and calendar, and add notes, to-dos, reminders and events, when you ask it to. How that assistant handles data is governed by its own privacy policy. You can turn the connection off at any time.
  • Sign in with Google and Apple: if you use these buttons, Google or Apple confirms who you are; only your name and e-mail address are shared with us.
  • Google Calendar: if you connect it in Settings, Notzz accesses only your calendar events and syncs them both ways. You can disconnect at any time in Settings.
  • Link previews: when you paste a link into a note, our server visits that page to show its title and image.

Google user data

Notzz's use and transfer of raw or derived user data received from Google APIs (including Google Workspace APIs) will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Notzz does not use, transfer, or sell Google user data — raw, aggregated, or derived — to create, train, or improve foundational or generalized AI or machine learning models. Google Calendar data is used only to sync events between Notzz and your own Google Calendar, and is never sent to any AI/ML service by Notzz. Only the AI connection you set up yourself (see above) can read your own calendar, and only when you ask it to, in order to show it back to you.

iPhone app

Reminder notifications are scheduled locally on your device, so the text and time of your reminders are downloaded to your phone. Allowing notifications is optional. The app does not access your location, contacts, camera or microphone.

Deleting your data

You can delete your account at any time from inside the app: Settings → Account → Delete my account. When an account is deleted, all of its data — notes, to-dos, reminders, events, settings, calendar and AI connections — is permanently removed from the database, and your uploaded images are removed from storage.
