Overview

WhenDidILast is built with privacy as a core principle. We believe your habits are personal and should stay that way.

Data Collection

We collect zero personal data. All habit tracking data (habit names, completion times, goals, and settings) is stored locally on your device only. This data never leaves your device:

It’s not transmitted to any servers
It’s not backed up to the cloud
It’s not accessible to us or any third parties

Google Play Store

When you purchase the Pro version, the transaction is handled entirely by Google Play Store. We receive only:

Confirmation that a valid purchase was made
No personal information from the transaction

Google’s privacy policy applies to all purchase transactions. You can review it here.

Data Storage

All app data is stored locally using Android’s built-in storage. This data:

Remains on your device
Can be deleted by uninstalling the app
Is not accessble without physical access to your unlocked device

Data Deletion

To delete all your data simply uninstall WhenDidILast from your device.

Note that this permanently removes all habit data. We cannot recover it because we never had access to it.

Third Party Services

WhenDidILast does NOT use:

Analytics services (no Firebase, Google Analytics, etc.)
Advertising networks
Social media integrations
Cloud storage or backup services
Any third-party SDKs that collect data

Changes to This Policy

If we ever change our privacy practices, we will update this policy and notify users through an app update notice. Any changes will maintain our commitment to user privacy.

Your Rights

Since we collect no data:

There is no data to access
There is no data to delete
There is no data to export
There is no data to correct

Your habit data belongs to you and exists only on your device.
