The individual or business operating Ketoz (the "Service"; the "Operator") treats your personal information with care, and sets out its privacy practices below.
| Item | Purpose | Where it is kept |
|---|---|---|
| Barcode camera view | Barcode recognition | Processed on your device only; never sent to our servers |
| Submitted photos (nutrition label, product front) | Automatic recognition and/or registration of nutrition information after review | Our servers |
| Unique identifier | Preventing duplicate participation, awarding points, linking submission history | A number issued automatically without signing up |
| Email address and password (optional, when linking an account) | So you can keep your points when you change devices | A separate authentication system |
| Likes / dislikes / short comments | Community features | Stored on our servers (linked only to the unique identifier) |
| Keto Diary entries (products eaten, net carbs and amounts, by date) | Showing your net carb total for the day and success rates over time | Stored on our servers (linked only to the unique identifier) |
| Check-in and activity records | Daily check-in, enforcing daily usage limits | Stored on our servers (linked only to the unique identifier) |
| Push notification token (if you allow notifications) | Notifying you when a product you submitted has been reviewed | Stored on our servers; deleted when you turn notifications off |
| Recent scans and favourites | Convenience | Stored on your device only; not sent to our servers |
| App usage events and error logs | Understanding how often features are used, diagnosing app errors | Handled by analytics and crash reporting services |
| Advertising identifier | Serving ads and controlling how often they appear | Handled by the advertising service |
We do not collect directly identifying personal information such as your name, legal name, phone number or address. The Service is designed to be used without signing up, and linking an account (registering an email address) is optional.
Permissions are requested only when you use the relevant feature, and declining them still leaves the rest of the app usable.
| Company / service | Purpose | Information shared |
|---|---|---|
| Google (servers, sign-in, storage) | Storing data, handling sign-in, running app features | All server-stored items listed in section 1 |
| Google (AI photo analysis) | Automatically reading values from nutrition label photos you submit | The nutrition label photos you upload |
| Anthropic (backup AI photo analysis) | Performing the same task as a fallback when the above recognition fails or servers are busy | The nutrition label photos you upload |
| Google Firebase (analytics and crash reporting) | Statistics on how often features are used, diagnosing app errors | Screen and feature usage events, error logs, device and app version information |
| Google AdMob (advertising) | Serving ads | Advertising identifier, device and usage information |
These services operate servers overseas (including in the United States), so your information may be transferred and processed outside your country.
Nutrition label photos you upload are sent to the AI providers above for automatic recognition, and the results are reviewed by the Operator before being reflected in product information. For that reason, please take particular care not to upload photos unrelated to the product, such as faces or identity documents.
Short comments and submitted photos may be visible to other users. Inappropriate content may be deleted on receipt of a report or at the Operator's discretion. Nutrition information approved in review (product names and values) becomes public data within the Service; individual deletion requests will be reviewed and handled.
If you have not linked an account, deleting the app or resetting your device makes it impossible to identify you, and your data — including your Keto Diary entries and points — cannot be recovered. If you want to keep your records, we recommend linking an email address in the app. If you would like your data deleted, please contact us at the address below and we will handle it after verification.
You may request access to, correction of, deletion of, or suspension of processing of your personal information. Contact: contact@ketoz.app
The Service is not directed at children under 14, and we do not knowingly collect personal information from children.
Z Points ("Z") are an internal virtual metric within the Service, provided as a reward for activity in the Service (contributing photos, registering information, viewing ads and so on). Please note the following.
We apply a reasonable level of technical safeguards, including access control, separation of the administrator account, and running sensitive processing only on our own servers.
If this policy changes, we will give notice through in-app announcements or this page. The amended policy takes effect when posted.
