Who provides this app
Weightwise is provided by Timastra LLC, 5830 E 2nd St, Ste 7000 #38687, Casper, WY 82609, US. Privacy questions can be sent to support@timastra.com.
This policy explains the app’s data use, including optional features and differences between supported platforms.
Health and meal records
Weight, goals, meals, photos, custom foods, sleep, exercise, habits, imported health summaries and personalized daily-plan feedback stay on your device in local storage. Food recognition, nutrition-label reading and barcode matching run on the device. Photos and recognition results are not uploaded for recognition. Review and correct readings and suggestions before using them. They support personal tracking and do not provide medical or allergen advice.
Optional health access
With permission, Apple Health or Health Connect provides read-only weight, steps, active energy, sleep and exercise information, including older history where you allow it. Imported records stay locally. Health data is not used for advertising.
Automatic and background imports
While a source is connected and Automatic health import is on, Weightwise checks for new records when you open or return to the app, every 20 minutes while it is open, and in the background about every six hours when the operating system allows. On Android, background reads use Health Connect's separate background-access permission. Turn off Automatic health import, disconnect the source or revoke access at any time to stop future imports; remove existing imported copies separately.
Device permissions
On Android, Weightwise asks for physical-activity (activity recognition) permission when you connect Health Connect, because Android requires it for step and activity reads; other health records can still sync if you decline. Camera/photo access supports meal logging and notification permission supports reminders.
Purchases and SDK diagnostics
RevenueCat and Apple or Google process purchases and entitlements, including purchase information and technical identifiers; the app does not receive full card details. There is no separate product-engagement analytics, advertising or dedicated crash-reporting SDK. Google ML Kit can transmit app/device information, installation identifiers, usage/performance metrics and errors to Google even though recognition images and results stay on-device.
Security, backups and age
The optional PIN/biometric access lock does not encrypt the local SQLite database. Standard exports and backups are readable files; an optional password-protected backup uses AES-256-GCM. Android automatic backup and documented device-transfer mechanisms exclude app data; older copies are unaffected and iOS system backups depend on your device settings. Weightwise is not intended for children.
Retention and deletion
Edit individual entries or use Reset all app data to delete local records and managed meal photos. Turn off Automatic health import, disconnect health sources or revoke health permissions to stop future reads, including background imports; this does not delete the original platform health records. Remove manual backups, exported files and older system backups separately. Subscription, payment and SDK records are subject to RevenueCat, Apple and Google's retention and legal obligations. Uninstalling does not cancel subscriptions.

Support messages and your privacy choices
If you contact us, we receive your email address, message and any attachments you choose to send. We use them to respond, troubleshoot and handle privacy requests. Email and hosting providers process these communications and ordinary connection information. We retain correspondence as needed to resolve the request and meet applicable recordkeeping obligations; you may request deletion of correspondence.
You may request access, correction, export or deletion of personal information we hold, or raise an objection or withdraw consent where applicable. Local-only records must be managed on your device because we do not hold a remote copy. Optional device permissions can be revoked in system settings. Service providers may process data outside your country under their own policies; security also depends on your device and any destinations you choose for exports.
Contact and policy changes
Email support@timastra.com for Weightwise privacy questions. Include the app name and enough non-sensitive information to identify your request. Never send passwords, authentication codes, recovery keys or private health, financial or photo backups. We may need to verify ownership before releasing or deleting hosted records.
Material changes to the app's data practices will be reflected in this policy with an updated date and in the app where appropriate. Visiting this page is also covered by our website privacy policy.
