Terms of use & privacy

Last updated 21 October 2026

1. The software

You may use Notyrus to read, annotate and keep your own documents. You may not copy, modify, translate, reverse-engineer, decompile, redistribute, resell, rent, frame or embed it in another site, or use its code, design or icons to build another product, except where the law expressly allows it.

Notyrus includes open-source components that remain under their own licences; they are listed on the Credits & licences page. Nothing in these terms limits your rights under those licences.

2. Your documents and notes

Your books, notes, highlights, drawings, pictures and recordings stay where you choose to keep them:

With Google: in your own Google Drive. Notyrus reads and writes them directly from your browser.
Without an account: in your browser's storage on that device.

They are never sent to or stored on Notyrus servers. You own your content and are responsible for it, including having the right to the documents you open.

3. Privacy

Notyrus has no user accounts of its own and keeps no database of users or their content.

Google Drive access covers only the files Notyrus creates (kept in a "Notyrus" folder in your Drive) and the files you choose yourself with Google's file chooser. Notyrus cannot see anything else in your Drive. It uses this access only to list, open and save the books and notes you work with in Notyrus. Your files go directly between your browser and Google and never pass through or stay on Notyrus servers. Notyrus does not share, sell or transfer Google user data, and does not use it for advertising or to train any model. Notyrus's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Staying signed in: after you sign in with Google, your browser keeps an encrypted sign-in key in a secure cookie that your browser's scripts cannot read. When the one-hour Google access runs out, Notyrus's sign-in service uses that key to ask Google for a fresh one. The service stores nothing. Signing out in Notyrus deletes the key and tells Google to cancel it, and you can also remove Notyrus's access at any time from your Google Account (Security → Third-party apps & services).
The microphone is used only while you record a voice note.
Settings such as your last page or chosen tools are kept in your browser.
The site is served by Cloudflare, which may keep standard technical logs (such as IP addresses) to deliver and protect it.

4. No warranty

Notyrus is provided "as is", without warranties of any kind. Keep your own backups of important documents and notes. To the extent the law allows, Notyrus is not liable for any loss of data or other damages arising from its use.

5. Changes

These terms may be updated; the date above shows the latest version. Using Notyrus after a change means you accept the updated terms.
