Privacy First
Your data is stored only on your device and in your iCloud—we never see it. It is never sent to us for storage, backup, analytics, diagnostics, or any other reason.
The only way we can access your data is if you intentionally send it to us.
When You Save, Your Data Is
Saved on Device – Your data stays on your device, and is never sent to our servers
Backed-up to Files – Your Log/Endorsement is converted to JSON and exported to Files
Emailed – Your data is formatted into an email (readable text + attached file)—just tap send
Synced to iCloud (If enabled) - Your data is securely backed up and synced across all your devices with iCloud
