Privacy Policy
Last updated: April 21, 2026 · Version 2026-04-21
This Privacy Policy describes how BAWR Group LLC, a Delaware limited liability company ("we", "us"), handles information related to Wattro (the "Software").
1. Data Collection
The Software does not collect, transmit, or store personal data from your device for analytics or profiling. Battery, power, and system data read by the Software is processed locally on your device and is not transmitted to our servers.
2. No Telemetry
The Software contains no analytics, telemetry, tracking pixels, or crash reporting. The only network requests the Software makes are (a) license key activation and periodic re-validation (Pro users only) and (b) optional update checks.
3. License Verification
If you purchase a Pro license, your license key is verified by our license service (hosted on Supabase) during activation and re-validated periodically. The request transmits the license key itself; we return a short-lived signed certificate that the Software can verify offline for approximately 35 days. We do not receive device identifiers, usage data, or personal data as part of this verification.
4. Local Storage
The Software stores the following data locally on your device using macOS UserDefaults, the system Keychain, and a local SQLite database:
- Your settings and preferences
- Power history samples (wattage over time)
- Charge/discharge session records
- License activation status and signed certificate (Pro users)
This data is never transmitted anywhere. You can delete it by removing the app and its preferences.
5. Purchase & Payment Data
If you purchase a Pro license, we collect and store your email address, the Polar order identifier, and the purchase amount for the purpose of issuing and supporting your license. Payment card data is handled directly by Polar Software Inc. ("Polar") on Polar's checkout and is not transmitted through or stored on our servers. Polar acts as the Merchant of Record for Wattro Pro purchases and is an independent controller of the information you provide to them at checkout; their handling of that information is governed by Polar's Privacy Policy.
6. Data Retention & Your Rights
We retain license records for as long as necessary to provide the Software and to satisfy legal, tax, and accounting obligations. You may request access to, correction of, or deletion of the license record associated with your email by emailing privacy@wattro.app. Deleting a license record will deactivate the associated Pro license.
7. Children
The Software is not directed at children under 13 and we do not knowingly collect information from children.
8. Changes
If this policy changes, the updated version will be posted here with a new "Last updated" date and version identifier.
9. Contact
Privacy questions can be sent to privacy@wattro.app.
