Effective date: October 2026
Oil Control Index ("the App") is a skincare utility that estimates facial oiliness from a photo you provide and suggests a cleansing and product routine. This policy explains what the App does with your information. In short: it stays on your phone.
You take or choose a photo of your face to receive an oiliness assessment. The photo is analyzed entirely on your device using on-device image analysis. Photos are never uploaded anywhere — the App makes no network requests at all — so we never see, store, or have access to your photos.
The App does not require an account or sign-in. It contains no analytics, no advertising, and no third-party tracking software.
Your questionnaire answers and assessment history are stored only on your device, so you can review past results. Deleting the App permanently removes this data.
We collect no personal data, so we share nothing with third parties and sell nothing to anyone.
The App is a general-audience utility and collects no data from anyone, including children.
If this policy changes, the updated version will be posted at this same URL, and the effective date above will be updated.

Note: the Oil Index is a heuristic estimate, not a medical measurement, and does not diagnose skin conditions.
