Privacy Policy

The one-sentence version: your documents live on your iPhone. This app has no server, no accounts, and no analytics or advertising tools — we receive none of your data, and there is nowhere for it to go.

What Oda is

Oda is an iOS document scanning app made by an independent developer in Taiwan. It turns paper documents into searchable PDFs, with all processing done on your device.

What we do not collect

Where your documents are stored

Scanned images, recognized text, and document names are stored in the app's sandbox on your iPhone. Deleting a document, or uninstalling the app, removes that data from the device.

Two exceptions you should know about

1. Your iPhone's system backup. If you use iOS's "iCloud Backup" (the feature that backs up your whole phone), that backup includes Oda's data. It is stored in your own Apple account, held by Apple; we cannot access it.

2. Oda's optional iCloud backup (off by default). You can turn on iCloud backup in Oda's settings. When enabled:

• Documents are copied to your own iCloud storage (an app-specific iCloud container) held by Apple under Apple's terms — not our servers, and we cannot access it
• New and changed documents are backed up automatically; a sync also runs when the app goes to the background
• Deleting a document in the app also deletes its cloud copy
• When you turn backup off, you choose whether to keep or delete the copies already in iCloud
• If you have Advanced Data Protection enabled in your iPhone settings, this iCloud data is end-to-end encrypted and not even Apple can read it

Permissions: what we ask for and why

• Camera — to scan documents. Images go straight into the app's sandbox on your device
• Photo Library — to let you import document pictures from your photos. We only read the photos you actively select

Both can be revoked at any time in iPhone Settings; the corresponding feature stops working and everything else is unaffected.

A few things designed for privacy

• Location data stripped on import — photos imported from your library may carry EXIF metadata, including the GPS coordinates of where they were taken. Oda removes it before saving, so it never follows your documents into backups or exported PDFs
• Clipboard protection — when you copy recognized text, the clipboard entry is marked local-only (it does not sync to your other Apple devices via Universal Clipboard) and clears itself after 90 seconds
• Cropping can truly erase — edits are non-destructive (the original is kept and restorable), but if you cropped to hide something sensitive such as an ID number, you can choose to permanently delete the cropped-away part so it never reaches any backup

Purchases and payments

Unlocking the full version (one-time purchase or yearly subscription) goes through Apple's In-App Purchase system. Payment is handled by Apple; we never receive your name, card number, or any payment details. See Apple's Privacy Policy for how Apple handles that data.

Sharing and export

When you export a PDF or images, the file leaves through the iOS share sheet and goes only where you send it (save to Files, send to someone, print). Once shared, the receiving service handles it under its own policies.

Children's privacy

Oda collects no personal data from anyone, including children. The app is not directed at children under 13.

Your rights

Privacy laws (such as GDPR, CCPA, and Taiwan's PDPA) give you rights to access, correct, and delete personal data. For Oda: we hold no data about you, so there is nothing on our side to access, correct, or delete. Your data lives on your device and in your own iCloud — manage it directly in the app or in iOS Settings.

Changes to this policy

If the app's data practices ever change (for example, a future feature that needs a network), we will update this policy, change the effective date above, and flag significant changes inside the app.
