2. Description of Service
Currency Wiki is a currency conversion application that provides:
- Live and historical exchange rates

3. Your Anonymous Account
Anonymous Authentication
The App uses anonymous authentication. No personal account creation, email, or password is required. Your device is identified using a one-way cryptographic hash of your device identifier, which cannot be reversed.
Reinstalling the App
Your anonymous identity is kept in the iOS Keychain, so reinstalling the App on the same device returns the same account and allowances.
Session Management
Your session is managed through secure tokens that refresh automatically.
Using Pro on several devices
A Pro subscription can be used on up to 5 of your devices signed in to the same Apple Account. Use Restore Purchases on each device.

How ads use data, and how to refuse tracking or personalised ads, is explained in our Privacy Policy.
7. AI Scanner Service
Image Processing
Photos you scan are sent to our servers and read by Google Gemini, with OpenAI as a backup if Gemini is unavailable. Menu dishes can be translated into your app language. Photos are deleted automatically within 30 minutes, and the results are returned to your device.
Usage Limits
Free: 3 AI scans a week, plus 3 for each rewarded ad you watch. Pro: unlimited, subject to fair use (after 1,000 scans in a month, up to 30 a day). Free allowances reset weekly; Pro fair-use counts reset monthly. Rate limiting may apply to prevent abuse.
Accuracy Disclaimer
AI price detection and menu translation are provided for convenience only. Results may be inaccurate because of image quality, unusual price formats, handwriting or partly visible text. Always check detected prices and translations before relying on them, for example for payments or allergens.
