Privacy
Last updated 22 August 2026
Obsilide collects nothing. The Android app ships without the
INTERNET permission, so it cannot send your notes anywhere — not to us,
not to anyone. There is no account and no analytics.
What the app stores
Your notes stay in the app's private storage on your device, as plain files: a Markdown file holding the note's title and links, an ink sidecar holding your strokes, and a thumbnail image. Your pen and app preferences are stored alongside them.
Nobody but you and the apps you grant access to can read that folder. Uninstalling Obsilide removes it. If your device backs itself up to your own cloud account, that backup is governed by your device and cloud provider, not by us.
What we receive
- From the app: nothing. No usage data, no crash reports, no identifiers.
- From this website: nothing beyond what any web server sees. The site sets no cookies and loads no third-party scripts, fonts, or trackers.
- If you join the early-access list: only the email address you type, used only to tell you when a build is ready. One address, one purpose. Ask and it's deleted.
The early-access form is processed by Formspree, which stores the address you submit until we send that one announcement. Nothing else about you is collected with it, the list is never sold or shared, and it is deleted once the build has shipped. Write to the address below at any time to be removed sooner.
The site is served by GitHub Pages, which processes request logs (including IP addresses) as its infrastructure provider. See GitHub's privacy statement for what that involves.
If that ever changes
Features on the roadmap — syncing across devices, publishing a notebook to the web — would by definition move data off your device. They will be opt-in, they will be described here before they ship, and the app will keep working entirely offline if you never turn them on.
Children
Obsilide is not directed at children under 13, and since it collects no personal information, none is knowingly collected from them.
