Summary
The current Mathosis tracker stores habit records and preferences in your web browser using local storage. The app does not currently provide a Mathosis account or sync those records to a Mathosis cloud database. The page may still make technical requests to the hosting provider and to Google Fonts.
Information stored in your browser
Depending on what you enter, local site storage can include habit names and schedules, daily completions, sleep, water and mood entries, written reflections, profile display preferences, theme choices, reminder settings and internal onboarding state.
This information may reveal personal routines or wellbeing context. Anyone with access to your unlocked browser profile may be able to access it. Do not enter information you are uncomfortable storing on that device.
Network requests and technical logs
The website loads font files through Google Fonts. This sends a request that can include your IP address, browser information and the referring page to Google’s infrastructure under its own terms. The hosting provider may also process ordinary server and security logs needed to deliver the site, such as IP address, request time, requested URL, browser information and error details. Mathosis does not currently include a product analytics or advertising tracker in the application code reviewed for this notice.
How information is used
Browser-stored data is used on your device to render schedules, calculate summaries, display trends, restore preferences and produce exports. There is currently no server-side personalisation, advertising profile or sale of habit data by Mathosis.
Retention, export and deletion
Local records remain until you delete them, clear site storage or the browser/device removes them. Use the JSON backup feature before clearing storage if you want a copy. Use the app’s clear-data control, followed by your browser’s site-storage controls, to remove local records and preferences.
Because there is no Mathosis cloud account today, the project cannot restore browser data after it is deleted or retrieve it from another device.
Reminders and browser permissions
If you grant notification permission, your browser controls that permission. Current reminders rely on the web app and are not guaranteed to run when the app is closed. You can revoke notification permission in browser or operating-system settings.
Data sharing
Mathosis does not currently provide in-app social sharing, sell browser-stored habit records, or send those records to an advertising network. Data can leave your device when you choose to export it, share a screenshot or import/export through another service.
Children
Mathosis is not intentionally designed to collect cloud account data from children. Because age requirements and parental-consent rules differ by location, users who cannot legally consent to online services should use the site only with a parent or guardian.
Security and limits
No system is risk-free. Local browser storage is not a substitute for an encrypted vault or a backed-up database. Keep your device and browser account protected and export records you cannot afford to lose.
Contact and future changes
A verified privacy-contact address and the operator’s legal identity have not yet been published. See the contact page for the current route and launch requirements. Material changes—especially accounts, sync, analytics or billing—require an updated notice before those features go live.
