Otchi.

Privacy Policy

Effective date: September 3, 2026

Otchi (the “app”) does not collect what you save. It collects only anonymous usage statistics and crash reports, in order to improve the app. This policy explains what data the app handles and where that data stays.

1. What is not collected, and what is

The app has no sign-up or sign-in. There is no account identifying you, so the developer cannot know who you are. The links, notes, boards and images you save are not transmitted to the developer and do not leave your device.

Anonymous statistics and crash reports are collected within the scope of section 1-1 below.

1-1. Usage statistics and crash reports (Google Firebase)

To fix errors and understand which screens are actually used, the app uses Google Firebase Analytics and Crashlytics. The following is collected.

ItemContentsPurpose
Device identifier An anonymous ID newly generated per app installation; device model and OS version Statistics
Usage records Which screens were opened; app launch and exit times Statistics
Feature usage records Whether a link was saved and the outcome (success, duplicate, or failure with its reason); the service type of the saved link (e.g. Instagram, YouTube — the service name, not the address); whether it was a photo or a video; whether a saved item was reopened; whether a board was created; whether an item was pinned or deleted; whether a search was run and the number of results Statistics
Approximate location Country/region level, inferred from the connecting IP address (not precise location) Statistics
Error information Where the app crashed, and the execution path immediately before it Fixing errors

2. What the app stores on your device

The links you save and the information collected from them (title, author, excerpt, thumbnail image), the notes you write, the boards you create, and app settings such as your theme choice are stored only on your device.

This data is included in iOS device backups (iCloud backup, computer backup, direct transfer to a new device). Those backups are governed by Apple’s policies and the developer cannot access them.

Deleting the app deletes this data with it. You can also erase it directly from Settings ▸ Delete all data inside the app.

3. Backup files you create

Settings ▸ Export data produces a single file containing all of your saves and writes it to the Files app on your device. You create this file and you control it — it is not transmitted to the developer. If you share it elsewhere, managing it from that point on is your responsibility.

4. Notice regarding connections to external websites

The app’s core function is to retrieve titles, images and similar information from an address (URL) you paste or share. To do so the app connects to that website directly, so that website can see your IP address and browser information (User-Agent). This is the same kind of connection as opening the address in a web browser; the developer does not collect or receive that information.

The connections go to the address you specified and to the hosts of the images and preview data that page points at (for example a thumbnail CDN or a preview API). These lookups can occur not only when you save, but also when a saved item whose image is not yet on the device appears in a list. The developer collects nothing through these connections, and they do not pass through any developer server.

5. Children under 14

Because the app collects no personal data, no separate legal-guardian consent procedure applies to users under 14. The applicable age rating is the one shown on the App Store.

6. Changes to this policy

If this policy changes, this page is updated along with the app update. If cross-device sync is added in the future, that feature will operate only when you explicitly choose it, and this policy will be revised and announced before it takes effect.

7. Contact

This English text is a translation for convenience. In case of any discrepancy, the Korean version prevails.
