Privacy Policy
Last updated: 17 September 2026 · 日本語
This policy explains how information is handled in the iPhone app Odd Spot (the “App”).
1. The short version
The developer collects nothing about you. Your scores, records and settings are stored only on your iPhone and are never sent anywhere. There is no server operated by the developer.
The App does show advertising through Google AdMob. To deliver and measure those ads, Google receives certain information from your device. In practice that is the only part of this policy that needs explaining.
2. Information kept only on your device
The following is saved on your device. None of it is transmitted.
| What | Why |
|---|---|
| Best score | To show it on the title and result screens |
| Smallest color difference you told apart | Same |
| Number of plays | To decide how often to show an ad |
| Settings (mode, sound, haptics, language) | To keep them for next time |
Deleting the App erases all of it from your device. The developer holds no copy, because none was ever sent.
3. Advertising (Google AdMob)
The App is free, and it shows Google AdMob advertising to stay that way. Google and its partners may receive the following from your device in order to serve and measure ads and to prevent fraud.
| Type | Examples |
|---|---|
| Identifiers | Advertising identifier (IDFA), resettable device identifiers |
| Device information | Model, OS version, screen size, language, region |
| Ad information | Impressions, whether an ad was tapped, whether a video was completed |
| Coarse location | Country or region estimated from your IP address |
| Product interaction | App launches, taps, whether a rewarded video was watched to the end |
| Diagnostics | Crash logs, launch time, energy use |
This information is handled under Google’s own privacy policy. For details and to change your settings:
- Google Privacy Policy
- How Google uses information from sites or apps that use its services
- Google Ad Settings (personalised ads on / off)
App Tracking Transparency
On iOS, an app must ask for your permission before using the advertising identifier (IDFA). The App shows that request the first time you open it.
Choosing “Ask App Not to Track” keeps every feature of the App working exactly the same. The ads you see will simply not be based on your interests. You can change this at any time in Settings → Privacy & Security → Tracking.
If you are in the EU, the UK or Switzerland
When you use the App from a region covered by the GDPR, it shows Google’s consent screen (UMP: User Messaging Platform) the first time you open it and asks about advertising. You can change your consent at any time from that screen, reachable from “Ad settings” on the title screen.
4. Network use
The App makes no network requests other than to fetch ads. With no connection — in airplane mode, for example — the game plays normally; only the ads are missing.
5. Children
The App is not directed at any particular age group; it is made for a general audience. The developer does not knowingly collect personal information from children under 13. If a child uses the App, we suggest doing so with a guardian nearby.
6. Not a medical test
The App is a game about telling colors apart. It does not test or diagnose color vision, and it is not a substitute for a medical examination. The numbers it shows depend on your screen, the light around you and how you feel that day. If you have concerns about how you see color, please consult an ophthalmologist.
7. Deleting information
Deleting the App from your iPhone erases every record and setting stored on the device.
For information Google received for advertising, follow the methods described in the Google Privacy Policy. You can reset your advertising identifier in Settings → Privacy & Security → Tracking.
8. Changes to this policy
This policy may be revised as laws change or as the App changes. For a significant change, the date at the top of this page will be updated.
9. Contact

Replies are sent by email and may take some time.
10. Language
This is a translation of the Japanese original for convenience. If the two versions differ, the Japanese version governs.
