Privacy

We collect your email address and the link you came from (for example Instagram), only to tell you when Ajen opens and to see which videos bring people here. We never sell or share it. We keep it until the launch email is sent, or until you ask us to delete it. To see, change or delete your data, write to yoann@certideal.com.

Anonymous usage statistics in the app. To understand which parts of Ajen are useful, the app can send anonymous events to TelemetryDeck, a privacy-focused analytics service based in the EU: for example that a story was opened or a quiz was finished. These events contain no name, email, account, advertising identifier or location, and they cannot be linked to you. You can turn this off at any time in the app (badges screen, "Share anonymous usage"). Ajen has no account. Videos are streamed from our content provider (Bunny.net) over HTTPS.

Ad measurement (Meta). If you installed Ajen after seeing one of our ads on Instagram or Facebook, the app uses the Meta SDK to tell Meta that the install (and later a purchase) happened, so we can measure whether the ad worked. This only happens with your permission: the first time you open the app, iOS asks whether Ajen may track you across other companies' apps and websites. If you choose "Ask App Not to Track", Meta receives only limited, aggregated information. The SDK may use your device identifiers, and your purchase events, for this. You can change your choice any time in iOS Settings > Privacy & Security > Tracking. Ajen does not use Facebook Login and does not show ads.
