This Privacy Policy explains how the mobile application Yllo, published by Arynass IT, handles your information when you use the app on Android or iOS devices.
Data controller: Arynass IT. Contact: contact@arynass.com
We never collect or receive:
We do not have any database, server, or account system on our side. There is nothing to "log in to" and no profile of you on our servers.
All of the following is stored locally on your phone (SQLite database + AsyncStorage). It never leaves your device, we never see it, and no third party receives it:
Uninstalling the app removes everything in this section from your phone. You can also clear it from inside the app at any time (Profile → Delete scan history, and My Profiles → Delete).
Each time you scan a new product, the app sends an HTTPS request to
https://world.openfoodfacts.org containing only the
8–13-digit barcode of the product. No user identifier or personal
information is included.
Open Food Facts is a non-profit collaborative food database; its privacy policy is available at openfoodfacts.org/cgi/privacy.pl.
If — and only if — you choose to upgrade to Premium, the following flow happens:
These two services have their own data-controller status: we are not the controller of the data they store. If you cancel your subscription and want the residual purchase records erased, you must contact each provider directly using the links above. We can write to RevenueCat on your behalf — see Section 7.
Android (Google) and iOS (Apple) may automatically collect crash and performance reports under their own privacy policies. We do not have access to any identifying information in those reports.
All network traffic between the app and our third-party providers (Open Food Facts, RevenueCat, Google Play) is encrypted over HTTPS / TLS. Local data on your phone benefits from the operating system's sandbox protections (Android scoped storage, iOS app container).
Yllo is intended for users aged 13 or older. It is not directed to children under 13 and does not knowingly collect personal information from them. If you believe a child under 13 has provided personal data through the app, please contact us so we can help.
Because the app has no backend and no centralised account, the way to exercise data-protection rights is slightly different from a typical "delete my account" flow. Here's how it works:
You control it directly. To remove it:
To stop or cancel a Premium subscription, use Google Play (Play Store → Profile → Payments & subscriptions → Subscriptions). To request deletion of historical purchase records held by Google or by RevenueCat, contact them directly using the links in Section 3.2. If you'd like us to forward a deletion request to RevenueCat on your behalf, write to us — we will do so within 30 days.
Where you are protected by a privacy law that gives you the right to access, correct, delete, restrict, object to or port your personal data, you can exercise those rights against the data controllers listed in Section 3.2 (RevenueCat, Google) which are the only parties that hold any personally connectable data related to your use of Yllo. We do not hold any personal data on you.
You can always reach us at contact@arynass.com if you have a privacy question or need help; we will reply within 30 days. You also have the right to lodge a complaint with your local data-protection authority.
Because we do not run a backend, we do not transfer your data ourselves. The third-party providers used by the app (RevenueCat, Google) may process data outside your country, including in the United States, under their own legal frameworks (such as Standard Contractual Clauses approved by the European Commission). Their privacy policies are linked in Section 3.2.
We may update this Privacy Policy from time to time to reflect changes in the app or in applicable law. Any changes will be posted on this page with an updated "Last updated" date. Material changes will also be announced inside the app on next launch.
