Information PainCanvas Stores
Depending on how you use the app, PainCanvas may store the following information locally on your device:
- Pain entries and symptom details you enter
- Body regions, pain types, intensity scores, notes, tags, and factors
- Medication schedules, medication logs, and follow-up responses
- Flare episodes and related tracking data
- Reminder preferences and app settings
- Optional security settings, including biometric lock preference and a hashed recovery password
- Optional weather snapshots attached to entries
Where Data Is Stored
PainCanvas stores app data locally on your device using on-device storage. PainCanvas does not require an account and does not provide built-in cloud sync.
Analytics, Advertising, and Data Sharing
PainCanvas does not use third-party analytics for behavioral tracking inside the app.
PainCanvas does not sell your personal information and does not share your health records for advertising or marketing purposes.
Location and Weather
PainCanvas includes an optional "Auto-populate weather" feature (US only).
When this setting is enabled and you grant location permission, the app reads
your current location while saving an entry and sends those coordinates to the
US National Weather Service (api.weather.gov) to retrieve local
conditions. Your coordinates are sent directly to that service; PainCanvas
does not relay them to any other server. The app does not store your
coordinates — only the resulting weather reading (temperature, humidity,
pressure, and condition) is saved with the entry.
The National Weather Service is a US government service and only covers US locations. Outside the US, auto-populate is not available; you can fill in weather details manually or skip the weather card entirely.
If location permission is denied or the setting is turned off, entries can still be saved without a weather snapshot. No location history is stored by PainCanvas.
Notifications
If you enable reminders, PainCanvas may schedule local notifications on your device for medication reminders and related follow-ups. These notifications are generated locally on your device.
Exporting Data
PainCanvas may let you export reports or share information using apps and services available on your device. Once you choose to export or share data, handling of that exported data is controlled by the destination you select.
Backup Files
PainCanvas includes an optional backup feature that lets you export all of your health data as a portable JSON file and re-import it on any device or after a reinstall.
Backup files are not encrypted. The file contains your pain entries, medications, medication logs, tags, custom factors, templates, flare episodes, and weather snapshots in plain text. You are responsible for choosing a storage destination — such as a personal cloud drive or email account — that only you can access.
Once a backup file has been shared or saved to a destination outside the app, its handling is controlled by that destination. PainCanvas does not transmit backup files to any server.
Both creating and importing a backup require fresh biometric or password authentication within the app.
Security
PainCanvas supports optional biometric unlock and an optional recovery password. Recovery passwords are not stored in plaintext; the app stores a cryptographic hash instead.
No method of storage or transmission is completely secure, especially if your device itself is compromised.
Deleting Your Data
You can delete all locally stored PainCanvas data from within the app:
- Open PainCanvas on your device
- Go to Settings
- Tap Delete all local data and confirm
This permanently removes all records stored on the device, including pain entries, medication logs, follow-up outcomes, tags, custom factors, templates, flare episodes, weather snapshots, and app settings. No data is retained after deletion because PainCanvas does not store your data on any server.
Backup files you have previously exported to external destinations (such as a cloud drive or email) are not affected by this action and must be deleted separately from those destinations.
Children
PainCanvas is not directed to children under 13.
