Privacy Policy

Data Storage

All data you enter into Piru — including dose logs, substance preferences, daily dose settings, and app settings — is stored exclusively on your device using Apple's SwiftData framework.

No data is sent to any external server, cloud service, or third party.

Data We Don't Collect

• No personal information (name, email, phone number)
• No health or substance data
• No analytics or usage tracking
• No crash reports sent automatically
• No advertising identifiers
• No location data

Network Requests

Piru makes limited network requests solely to fetch and update substance information from public pharmacological databases (TripSit API, PsychonautWiki, and DailyMed/OpenFDA). These requests do not include any personal or usage data.

Data Export & Deletion

You can export all your data at any time via Settings → Export Data. The export is a local file that stays on your device unless you choose to share it.

Deleting the app removes all stored data permanently. There is no backup or recovery mechanism since no data exists outside your device.

Third-Party Services

Piru does not integrate with any third-party analytics, advertising, or tracking services.

Children's Privacy

Piru is not intended for use by children under the age of 18.

Changes to This Policy

If we ever change this policy, we'll update this page. Given our commitment to local-only data storage, significant changes are unlikely.
