Privacy Policy
The short version: DepthLog stores dive stamps on this device. It has no account, analytics, advertising SDK, or developer server. It does not compute NDL or a safety score.
Stamps
Site names, depths, durations, dates, and depth profiles stay in DepthLog's local app storage on the device. Passport PDFs you export are created on the device.
Purchases
Apple processes the DepthLog Pro Lifetime purchase. DepthLog can read StoreKit entitlement status. ToolBistro does not receive payment-card details.
Tracking and data sale
DepthLog contains no third-party analytics, advertising, cross-app tracking, or data-broker SDK. ToolBistro does not sell personal data.
Delete your data
Deleting DepthLog removes its local app storage from the device. ToolBistro cannot recover deleted stamps.
