Privacy policy · v1 · 24 August 2026
Your photography never leaves your phone.
Only the receipt does. Obtura is an iOS light meter for manual and film cameras, by Nesia, and it has no account, no usage analytics, no tracking and no advertising identifiers. Your photographs, camera profiles, readings, journal entries and location notes are stored on your device and are never transmitted. The one thing that leaves is an anonymous record of your purchase, and this page says exactly what is in it.
| Account or sign-in | none |

| What they receive | an anonymous receipt |
- What stays on your device
- Your photographs, camera and lens profiles, meter calibration, exposure readings, journal entries and the location notes attached to them live in Obtura's own storage on your phone. So do the words you speak or type to describe a shot: they are read by Apple's on-device model, inside the app, with no network request, and they are not kept after the recommendation is made. None of it is uploaded, backed up to us, or readable by us. There is no account to create, so there is nothing for us to attach it to.
- Purchases — the one exception
- When you buy Obtura Pro, Apple processes the payment. To validate that purchase and to remember that you are Pro, an anonymous purchase receipt and a random anonymous identifier generated for your installation are processed by RevenueCat, our purchase infrastructure provider. Those same anonymous records are what we read back in RevenueCat's dashboard as sales and cancellation totals — how many, not who — which is the only way we know whether the app works as a business. That is why the App Store privacy label declares Purchase History for two purposes: app functionality and analytics. The record itself contains no name, no email address, no photograph and no reading; it cannot identify you, and we cannot tell one buyer from another. It is the only thing Obtura sends anywhere. Apple and RevenueCat are the only third parties involved in Obtura at all — there is no product analytics SDK, no advertising network and no crash-reporting service, because we did not add any. The only thing anyone counts is receipts.
- Camera
- Obtura needs the camera because that is how it meters light and previews the frame. Images are processed live as they arrive and are not written down. A frame is saved only when you log a shot to the journal yourself, and a logged frame stays on the device. Refuse the permission and the app tells you it cannot meter rather than failing quietly.
- Location
- Optional, and only if you allow it. Location is read while you are using the app, at the moment you log a shot, so the journal can note roughly where you stood — to about a hundred metres. It is stored with that entry on your device and is never transmitted. Declining costs you the place name on an entry and nothing else.
- This website
- nesia.studio sets no cookies, runs no analytics and collects nothing. There is no consent banner because there is nothing to consent to. The site is static pages hosted on GitHub Pages, and the host may keep standard server request logs the way any web host does.
- Deleting your data
- Deleting the app deletes everything, because everything is in the app. There is no server-side copy to ask us about. Records of what you bought persist with Apple, under your Apple Account, as they do for anything bought from the App Store.
- Your rights
- Ask us anything about your data at the address below and you will get a straight answer. In practice there is essentially nothing to hand over, correct or delete, which is the point of building it this way.
- Changes & contact
- Privacy questions go to support@nesia.studio. This policy is version 1, effective 24 August 2026. Every change to it is committed to this site's public repository, so the full history of what we have promised is readable by anyone — for a studio making this particular claim, that is a feature rather than an accident.
