Privacy Policy

Last updated: July 5, 2026

Planthology is built local-first. Your plans, trips, photos, and settings live on your device. There are no ads, no analytics SDKs, and no tracking of any kind.

What stays on your device

Everything, by default: your everyday plans, trips, itineraries, reminders, custom categories, attached photos, and preferences are stored in the app's local database on your iPhone and are included in your normal device backups.

Location

Planthology uses your location only while you're using the app, and only to estimate drive times and to auto-complete plans when you arrive (if you've turned that option on). Drive-time estimates are computed by Apple's MapKit service; your location is never sent to servers operated by Planthology.

Trip sharing (optional)

If you choose to share a trip, that trip's data is end-to-end encrypted on your device before it is uploaded to the sharing backend. The decryption key travels only inside the invite link you send to your companions; the server stores ciphertext it cannot read. Trips you never share never leave your device.

Notifications

Leave-by alerts, reminders, and wrap-up prompts are local notifications, scheduled and delivered entirely on your device.

Third-party services

• Apple MapKit: map display and drive-time estimates, subject to Apple's privacy policy.
• National Park Service API: used only if you add your own free NPS API key to search trails; queries go directly from your device to nps.gov.

Your choices

You can delete any plan, trip, or photo at any time, bulk-delete past history from Settings → Clean Up History, and revoke location or notification permissions in iOS Settings. Deleting the app deletes its local data.

Children

Planthology is not directed at children under 13 and collects no personal information from anyone.

Changes

If this policy changes, the update will be posted on this page with a new date above.
