OcuScreen is built around one simple idea: what happens on your phone, stays on your phone. This page explains what we do (and don't) collect, why we ask for the permissions we do, and how you can remove everything at any time.

What OcuScreen is — and isn't

OcuScreen is a wellness and screening tool. It is not a medical device. It has not been reviewed or cleared by the FDA, the EU MDR system, or any other medical regulator. It does not replace an eye doctor.

OcuScreen helps you notice things about your vision and the look of your eyes, between visits to a real eye-care professional. It cannot determine any condition, and nothing in the app substitutes for seeing an optometrist or ophthalmologist. If you're worried about your eyes or your vision, please see a doctor.

Where you are matters

OcuScreen adjusts which privacy rules apply to you based on your region:

EU/EEA, UK, and Switzerland: handled under GDPR.
US and Canada: handled on an on-device-first basis. OcuScreen is not a HIPAA-covered service.
Everywhere else: OcuScreen applies whichever of the above rules is strictest.

Permissions we ask for — all of them optional

OcuScreen only asks for what a given check actually needs, and every permission below is optional. Say no to any of them, and the rest of the app keeps working.

Camera

Some checks take a photo of your eyes, and the camera also acts as a simple distance guide during checks that need you a certain distance from your phone. Photos stay on your iPhone — OcuScreen never sends them anywhere unless you actively choose to share one yourself.

Microphone (optional)

Three checks let you answer out loud instead of tapping the screen. The microphone stays off unless you turn this on, and nothing you say is ever recorded or uploaded — your speech is recognized entirely on your iPhone.

Location (optional)

Location powers the "find eye care nearby" map, centering it on where you are. Without it, the map still works — you can just search for a place manually instead.

How your data is stored

Everything OcuScreen records — your results and any photos — stays on your iPhone, protected by the system's built-in file encryption. None of it is uploaded to any OcuScreen server.

Your credit balance is the one exception, and it isn't health data — it's stored in your iPhone's Keychain. With iCloud Keychain turned on, that balance can follow your Apple ID to your other devices. Your photos and results never go to iCloud; only your purchase and credit record does.

No tracking, no ads, no analytics

OcuScreen reads no information from Apple Health, gathers no usage statistics, and carries no advertising and no tracking of any kind. We're not in the business of watching what you do — we're just here to help you keep an eye on your eyes.

OcuScreen asks for your consent once, before you use it for the first time. There's no maze of per-purpose toggles, because your data is never reused for anything beyond the check you ran it for.

Deleting your data

Deleting the OcuScreen app deletes everything it stored on your device — every result, every photo. Right now, there's no in-app option to erase individual results one at a time; removing the app is how you clear everything at once.
