Privacy policy

Version of 2 October 2026

In short

Betterest keeps what you enter on your phone. The only things it sends are anonymous usage data and crash reports, described below, without your name and without anything you wrote. You can turn that off in Settings, and if your App Store is in the EU or the EEA, nothing is sent unless you say yes. If you buy Betterest, Apple handles the payment and RevenueCat keeps track of what you bought.

Who is responsible

Etienne Baume, Switzerland. Questions and requests: contact@aeranova.ch

What stays on your phone

Your name, your activities (including the ones you add), your times and workdays, your evenings, lunch breaks and morning scores.
They are stored in Betterest’s own storage on your iPhone, and they are part of your iPhone backup if you make one, which Apple encrypts. Deleting Betterest deletes them.
Betterest has no account and no server of its own.

Apple Health

If you allow it, Betterest reads your sleep and heart rate variability to show them next to your evenings. It only reads and never writes. The numbers stay on your phone: they are never sent anywhere, not with usage data and not to anyone else, and never used for advertising.

Screen Time

If you set up the shield, you choose your work apps in Apple’s own picker. Apple gives Betterest an anonymous token for them, not their names, and Betterest cannot see what you do in them. None of this leaves your phone.

Notifications

Reminders are scheduled on your phone. No push server is involved.

Buying Betterest

The first month on the yearly plan is free; then Betterest is paid, through Apple. Apple handles the payment: Betterest never sees your name, your Apple ID or your payment details.

What RevenueCat receives: to tell the app what you have, RevenueCat receives Apple’s record of your purchases: which plan, when it started, renews or ends, its price and currency, and your App Store’s country, with a random ID made on your phone. It is not linked to your name; Betterest has no account.
Founding members: the app asks Apple which version of Betterest you first installed, so that everyone who installed it while it was free keeps everything. The answer stays on your phone.
Who processes it: RevenueCat, Inc. (USA), on Betterest’s behalf under a data processing agreement with standard contractual clauses.
Why: to give you what you paid for (Art. 6(1)(b) GDPR, and the Swiss Federal Act on Data Protection).
How long: as long as Betterest is sold through RevenueCat. You can ask for your purchase records there to be deleted at any time; Apple keeps its own.

Usage data

Betterest sends anonymous usage data, so it can see whether it helps and get better. You can turn it off at any time in Settings → Usage data; from then on nothing is sent, crash reports included. If your App Store is in the EU or the EEA, Betterest asks first and sends nothing unless you say yes.

What is sent: that the app was opened, and events such as closing the day, the decision for an evening, a lunch break or an idea on a day off, the morning’s score from 1 to 5, how drained you were, how many times work apps were opened, which of Betterest’s own activities it was about, each week’s count of work-free days with your weekly goal, whether the plans were shown, which plan you chose and whether the free month started (never the price), and where you heard about Betterest if you answer that question. Also what any app sends along: the app version, iOS version, device model and screen size, language, time zone, and whether the phone is on Wi-Fi or mobile data.
Crash reports: if Betterest crashes, the next launch sends what kind of crash it was, its technical message and where in Betterest’s code it happened, with the same app and device details. Nothing you entered is in it.
What is never sent: your name, the text of activities you added, anything from Apple Health, which work apps you chose, or anything you type.
Who processes it: PostHog, Inc. (USA), on servers in the EU (Frankfurt, Germany), on Betterest’s behalf under a data processing agreement with standard contractual clauses.
Not linked to you: events carry a random ID made on your phone. There is no account, no profile of you, no advertising and no tracking across apps. Your IP address reaches PostHog, as it does with any connection. Betterest’s project is set not to store it.
Why: to see whether Betterest helps and where it gets in the way, and to find and fix crashes. If your App Store is in the EU or the EEA, the basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time in Settings. Elsewhere it is Betterest’s legitimate interest (the Swiss Federal Act on Data Protection, and Art. 6(1)(f) GDPR), and you can object at any time by turning usage data off in Settings.
How long: deleted after at most 12 months.

Your data, your rights

Export: Settings → Export your history gives you your evenings and lunch breaks as a spreadsheet.
Delete: deleting the app deletes everything on your phone. Turning off usage data stops anything more from being sent.
You have the right to access, correct and delete your data, and to object to usage data. Usage data and purchase records are not linked to you, so they can only be found by their random IDs: Settings shows the usage data one while sharing is on, and purchase records are found by the order ID on Apple’s receipt email. Write to contact@aeranova.ch.
You can complain to the Swiss Federal Data Protection and Information Commissioner (FDPIC) or, in the EU, to your data protection authority.
