Privacy Policy – Commute Calculator
Effective date: 8/17/25
Contact: douglas.wiseman@gmail.com
Overview
Commute Calculator is a utility app that runs entirely on your device. It does not require an account and does not send your data to our servers or third parties.
Data We Collect
On-device commute data you enter (e.g., jobs, start time) is stored locally on your device.
Exports are user-initiated only. When you choose Export Daily Snapshot, the app saves files to a location you pick using the system file picker (e.g., Google Drive, iCloud Drive, local storage).
No background uploads, no analytics, no ads.
What’s in an Export
To help verify authenticity, the snapshot includes:
Timestamps (UTC & local), timezone, and app version.
A SHA-256 hash file that matches the JSON contents.
Device metadata: model, OS version, app bundle ID, and (Android only) the Android ID, and (iOS only) the Identifier for Vendor (IDFV). These values are written only into the files you export and are not sent to us.
If you prefer to remove Android ID/IDFV from exports, you can do so in Settings. (If you haven’t added a toggle yet, you can remove the lines and update this sentence.)
Data Sharing
We do not share your data with third parties.
Permissions
The app uses the system file picker to read/write the files you select. It does not request broad file access.
Data Retention & Control
All commute data remains on your device until you delete it.
You can clear records in the app at any time.
Exported files remain wherever you saved them; delete them from that storage if you no longer want them.
Children’s Privacy
The app is intended for general audiences and not directed to children under 13.
Changes to This Policy
We may update this policy as the app evolves. We will update the “Effective date” above.
