PUP
Bowel movement logs are personal health information. Before choosing a tracker, look beyond the feature list and understand what happens to your data.
If privacy is your priority, PUP is a private, offline-friendly poop diary designed for quick daily logging.
A privacy checklist
Is an account required?
An app that lets you start locally without an account collects less identifying information at the beginning. If an account is required for sync, check what profile data is attached to your logs.
Where is data stored?
Look for a clear explanation of local storage, cloud sync, backups, and device changes. “Encrypted” is not enough unless the policy explains what is encrypted and when.
What analytics are used?
Check whether the app uses advertising identifiers, third-party analytics, session recording, or crash reporting. Health details should not be sent to analytics tools unless the policy clearly explains why and how.
Can you export and delete?
Useful controls include exporting your records, deleting an account, and deleting local data. Check whether deletion includes backups and synced copies, and how long the process takes.
Is location optional?
Location can make a log more useful, but it should not be required for basic tracking. Check whether precise location is collected, stored, or shared.
Is the policy current and specific?
Read the date, data categories, sharing section, retention period, and contact details. Avoid relying on a “privacy-first” label without evidence.
How PUP approaches this
PUP is designed to let you start without an account and log offline. Sync is optional, and location and notes are optional fields. The PUP privacy policy explains the app’s storage, analytics, deletion, and export behavior in detail.
Those are product claims, not a substitute for reading the policy. Recheck them before relying on any health app, especially after an update.
Comparing apps fairly
When comparing trackers, record the same fields for each app: account requirement, offline support, storage location, encryption, analytics and ads, location handling, export, deletion, policy date, and price. Test the current version on the platform you use and link every claim to the app’s own documentation.
