Privacy Policy for Lockoon

Lockoon does not collect anything you write in it. To learn whether our ads work, the app uses Meta's SDK, and to learn where people get stuck in the app, it sends anonymous usage events to PostHog. Both receive only a small amount of technical information. This page lists exactly what that is.

WHAT STAYS ON YOUR DEVICE Everything you enter — your seasons, your goals, what you tick off, your daily notes and your archive of finished seasons — is stored only on your device. It is never uploaded. Lockoon has no account system and no server of its own.

ADVERTISING MEASUREMENT (META SDK) Lockoon includes the Meta (Facebook) SDK so we can tell whether people who saw a Lockoon ad on Facebook or Instagram went on to install and open the app. When you install and open Lockoon, the SDK sends Meta Platforms, Inc.:

that the app was installed or opened, and when
technical device information: device model, iOS version, language, time zone, screen size and app version
an identifier the SDK creates for this installation of the app
your IP address, which every internet request carries
crash reports from the SDK's own code It does not send your goals, notes, ticks, seasons or anything else you enter. Lockoon never asks for permission to track you, so the SDK cannot read your device's advertising identifier (IDFA), and Lockoon has turned that collection off. We use the results only in aggregate, to see how many installs an ad brought in. Meta handles this information under its own policy: https://www.facebook.com/privacy/policy

ANONYMOUS USAGE ANALYTICS (POSTHOG) To see which parts of the app work and where people give up, Lockoon sends anonymous usage events to PostHog (PostHog Inc., stored on its EU servers in Frankfurt). An event says that something happened, for example "a season was created", "a step was ticked" or "the Pro screen was shown", with a few numbers such as the season length, the number of goals or the day of the season. Alongside the events PostHog receives:

technical device information: device model, operating system and version, language, time zone and app version
a random identifier created for this installation of the app, so events from the same install can be counted together
your IP address, which every internet request carries; PostHog is set to discard it and not to look up your location from it It never receives the names of your seasons or goals, your notes, or anything else you type. There is no account, no profile of you, no screen recording and no tracking across other apps or websites. We use the results only in aggregate. PostHog's policy: https://posthog.com/privacy

PURCHASES (LOCKOON PRO) Lockoon Pro is sold through Apple's App Store. Apple handles the payment; we never see your card or Apple Account details. Whether your subscription is active is checked on your device with Apple's StoreKit, and the app keeps only that yes/no answer on the phone. No payment information is sent to us or to Meta. The anonymous analytics above record that the Pro screen was shown and whether a purchase was started, completed or cancelled, never who you are or how you paid.

ANDROID The Android version of Lockoon does not include the Meta SDK and sends no information to Meta. It sends the same anonymous usage events to PostHog as described above. On Android, Lockoon Pro is sold through Google Play: Google handles the payment, and whether your subscription is active is checked on your device with Google Play Billing. We never see your payment details.

WHAT WE DO NOT DO We do not sell your information. We do not build profiles of you, show ads inside the app, or ask you to sign in.

EXPORT Settings includes an export that writes your own history to a CSV or JSON file and hands it to the iOS share sheet. Where that file goes afterwards is entirely your choice; the app does not send it anywhere.

NOTIFICATIONS If you turn reminders on, Lockoon schedules local notifications on your device. These are generated on the device and are not push notifications; no information is sent off the device to deliver them.

DELETING YOUR DATA Settings includes "Delete all data", which permanently erases everything the app has stored, including your archive. Deleting the app removes it all as well. Lockoon holds nothing about you anywhere else. The anonymous PostHog events are not tied to you, so they cannot be looked up by person; they are kept for at most a year. For information Meta received through its SDK, see the Meta policy linked above.

CHILDREN Lockoon is not directed at children under 13 and we do not knowingly collect information from them.
