The short version. Avesia has no account and no server. Your medications, doses, eye-pressure and blood-pressure readings, symptoms, home check results, appointments and photos are stored on your device and are never transmitted to us or to anyone else. We cannot see them. We do not sell or share any of your information, and there is no advertising or analytics in the app.
Avesia is an independent app. In this policy, "we" and "us" mean the developer of Avesia, and "the app" means the Avesia iOS application. Contact: rajveer2023.singh@gmail.com.
Everything you enter is written to storage that belongs to the app on your own device. That storage is a file in the app's private Documents area, with photos saved as files alongside it. There is no Avesia account, no login, and no Avesia server for that data to go to.
That storage includes:
Some of this is health information. We treat it as the most sensitive data in the app, which is why the design keeps it on the device rather than synchronising it anywhere.
Because this data lives in the app's Documents area, it is included in your iCloud or local device backups if you have backups turned on. Those backups are covered by Apple's terms and your iCloud settings, not by us. We have no access to them. If you restore a device from a backup, your Avesia data comes back with it.
Avesia can export your data as a JSON file so you can keep a copy or bring it to an appointment. Once you export it, that file is yours and goes wherever you send it. If you share it by mail, by message, or into another app, it is no longer protected by Avesia, so treat it as you would any medical record.
One optional feature makes network requests. It is off unless you turn it on, and it does not send your health data. Everything else in the app, including reading a medication label with the camera, works with no network at all.
| Feature | What is sent | To whom | When |
|---|---|---|---|
| Local dry-air & air-quality info (optional) | An approximate location: your coordinates rounded to two decimal places (about 1 km), or the name of a city you pick from a list. Nothing else. No medications, readings, symptoms or identifiers. | Open-Meteo, a weather and air-quality service | Only while you have this feature switched on, roughly every few hours and when you pull to refresh. You can turn it off at any time in More → Settings. |
As with any internet request, the provider above necessarily sees the network address the request came from, and uses it to route the response. We do not receive that information, and we have no agreement with them to receive anything about you.
Reading a medication label is done entirely on your device: the text recognition software is included in the app, so no photo and no request leaves your iPhone when you scan a bottle.
Under More → Help improve Avesia, the app can show you a short plain-text summary of how you have used it: how many times each tab was opened, how often features like the report, a vision self-test, the label scanner, a taper or the drop-spacing timer were used, how many days and sessions, and the app and iOS version. It is shown to you in full, before anything happens, and a button then hands it to the standard iOS share sheet so you can decide where it goes. You can also close the screen and send nothing.
Three things about it are worth stating plainly:
If you never open that screen, the counts simply sit on your device with the rest of your data and are deleted with the app.
You can decline or later revoke any of these in iOS Settings. Declining them does not stop the rest of the app from working.
Avesia is intended for adults managing their own eye care. It is not directed at children under 13, and we do not knowingly collect information from them. In fact we do not receive users' information at all.
Because your data is on your device and not on our servers, you control it directly:
We cannot fulfil a request to access or delete your data on your behalf, because we do not hold it. If you are in a jurisdiction with rights under laws such as the GDPR or the CCPA/CPRA, those rights still apply. They are simply exercised on your own device, and there is no data of yours in our possession to which they could otherwise attach.
Avesia relies on your device's own protections. Its data file is written with iOS file protection so that it is encrypted at rest and unavailable until you have unlocked the device once after a restart, and writes are made atomically so an interrupted save cannot leave a half-written file. No security measure is absolute: if someone can unlock your device, they can open your apps, so a passcode or Face ID is the most important safeguard for this information.
Avesia is an educational self-management aid. It does not diagnose, treat or screen for any condition, and its home checks are not eye examinations. Never start, stop or change a medication because of this app. Follow your ophthalmologist's instructions. Sudden vision loss, new flashes or floaters, a curtain across your vision, or severe eye pain need urgent in-person care.
If this policy changes in a way that affects what leaves your device, we will update the date at the top and describe the change here. Material changes will also be surfaced in the app.
