Privacy & your records

Updated October 14, 2026.

Your sample data stays here

Sample names, dates, weights and notes are stored in this browser using IndexedDB. They are not sent to our server. There is no account or automatic cloud sync. Clearing site data, private browsing expiry or browser storage eviction can remove records. Keep JSON backups somewhere you control.

Imports are processed in your browser. Downloads contain the sample information you entered. You choose where to store or share those files.

Minimal task counts

When a weigh-in is saved or CSV is exported, the site sends only the action name and a test-traffic marker to a same-origin endpoint. We retain daily aggregate counts for up to 90 days, separately for tests. We do not store sample data, user identifiers or IP addresses in this counter. Counts are actions, not unique people.

The endpoint respects Do Not Track and Global Privacy Control request signals. Cloudflare necessarily processes requests to deliver and protect the site, including network information such as IP addresses; that is separate from our aggregate counter. Browser and hosting operation are not anonymous to every network provider.

No advertising scripts at launch

No Google Analytics, Tag Manager, advertising pixels or third-party fonts are loaded. No affiliate links are active at launch. If those arrangements change, this page and relevant disclosures will change before they are enabled.

Questions

See the about and contact page. Do not put private information into sample names or notes unless you want it included in your own backups.
