Your routines and tasks, completion and skip history, numeric logs and short notes, habit situation notes, and app settings are stored in the App's storage on your device. Backups for recovery from file damage (the most recent 7 days) are also created on the same device. The summary shown in the Home Screen widget is kept in the app group storage on the same device.
We cannot see this information. However, if you have iCloud Backup turned on for your iPhone, it may be included in Apple's device backup, which is governed by Apple's policies.
We send usage statistics to the analytics service Mixpanel to improve the App.
| Item | Details | Purpose |
|---|---|---|
| App usage | App launches, onboarding progress, routine creation (type, number of tasks, duration, repeat pattern, time of day), timer start and finish, check-offs and goals met, notification opens, paywall views | Analyzing how features are used and improving the service |
| Device identifier | A random ID created by the Mixpanel SDK when the App is installed (not the device advertising ID or the IDFV) | Grouping events from the same device |
| Purchase history | Product ID purchased, price, currency, and whether a free trial was used | Analyzing subscription usage |
| App environment | App version, build number, language, and subscription status | Identifying issues by version |
| AI Lento usage | Number of chats and turns, the type and task count of suggested routines, chips tapped, "don't like it" reason category, and whether consent was given or the daily limit was reached (chat content is not sent) | Improving AI Lento |
What we do not send: routine names, task names you enter yourself, log values, notes, or the contents of situation tags. A task name is sent only when it exactly matches a suggestion built into the App. Names you write yourself are only counted, never sent.
IP-based location estimation is turned off. We do not track you for advertising or combine this information with data from other companies. This information alone cannot identify you.
