ONE MINUTE HABIT
Privacy Policy
IN SHORT
One Minute Habit has no account and no server of its own. Everything you enter in the app — your habits, your times, your “why” and the days you completed — stays on your device. What leaves the app is an anonymous count of the features being used. Your habits and your “why” never leave the device.
Everything else is spelled out in detail below.
1. Controller
Jan Goldstraß
c/o IP-Management #46676
Ludwig-Erhard-Str. 18
20459 Hamburg
Germany
Email: [email protected]
No data protection officer has been appointed; the legal requirements for that are not met.
2. Data in the app
2.1 What is stored on your device
The app stores the following in a local database on your device:
- your habits and their names
- the times and reminders you set
- your optional “why”
- the days you marked as done (streak and history)
- settings such as appearance and language
This data is not transmitted to me. I have no access to it. There is no account, no sign-in and no synchronisation via a server.
If you use your iPhone’s iCloud backup, this data is included in your device’s backup — encrypted, with Apple, not with me. Apple’s privacy policy applies to that.
You can delete the data yourself at any time: in the app under Settings → Privacy → Delete all data, or by removing the app from your device. In both cases the data is gone and cannot be recovered.
2.2 Reminders
The daily reminders are local notifications. They are scheduled and triggered on your device. There is no push server, no device token and no transmission of your reminder times to me or to third parties.
2.3 Anonymous usage analytics
The app counts which features are used and whether something goes wrong, so I can understand where the app gets stuck and what it could do better.
- What is sent: events such as “onboarding step viewed”, “minute started”, “minute completed”, “paywall opened”, “purchase failed”, plus counters, yes/no values, durations in seconds as well as technical details such as app version, operating system version and device type.
- What is not sent: the names of your habits, your “why” and anything else you type in yourself. No advertising ID, no tracking across other apps or websites, no email address.
- Processor: PostHog. The data is processed on servers in the European Union (eu.i.posthog.com, data centre in Frankfurt am Main). The provider is PostHog, Inc., 2261 Market Street #4008, San Francisco, CA 94114, USA. A data processing agreement pursuant to Art. 28 GDPR is in place with PostHog. Where data is exceptionally transferred to the USA, this is done on the basis of the European Commission’s Standard Contractual Clauses.
- Identifier: The events are assigned to a randomly generated device identifier, so that steps belonging together are recognisable as one sequence. This identifier is not linked to your name, your email address or an advertising ID, and a new one is issued when you delete the app.
- Legal basis: Art. 6(1)(f) GDPR. My legitimate interest is to find bugs and to improve the app on the basis of actual use, without setting up accounts or personal profiles for that purpose.
- Retention period: The events are stored at PostHog for a maximum of 12 months and are deleted automatically afterwards.
- Objection: You can object to this processing at any time — an informal email to [email protected] is enough. See section 5 for details.
2.4 Buying One Minute Pro
The purchase itself runs through Apple. Apple is your contracting party for the purchase; Apple gives me no information about who bought, only aggregated sales figures. Apple’s privacy policy applies to payment processing.
To recognise inside the app whether Pro is unlocked, and to let you restore purchases on a new device, the purchase status is managed via RevenueCat. The provider is RevenueCat, Inc., 1 Letterman Drive, Building C, Suite C3-800, San Francisco, CA 94129, USA. This involves processing a randomly generated, anonymous user identifier, Apple’s purchase receipt and technical details such as app and operating system version. The app does not transmit a name, an email address or payment data.
The legal basis is Art. 6(1)(b) GDPR (performance of the contract for the Pro features). A data processing agreement pursuant to Art. 28 GDPR is in place with RevenueCat; the transfer to the USA is based on the European Commission’s Standard Contractual Clauses.
2.5 Rating prompt
The app may ask you for an App Store rating via Apple’s built-in dialog. The dialog comes from Apple, is displayed by Apple, and I do not learn whether or how you answered it.
3. This website
3.1 Server log files
When you open this website, the hosting provider automatically processes data that your browser transmits: IP address, date and time of the request, page requested, amount of data transferred, referrer as well as browser and operating system identifiers. This is technically necessary in order to deliver the page and to keep it secure.
I do not receive these log files and keep no records of my own about your visit. The data stays with Cloudflare, which processes it on my behalf and deletes it in line with its own retention policy as soon as it is no longer needed for those purposes.
The legal basis is Art. 6(1)(f) GDPR; the legitimate interest lies in the technically sound and secure operation of the website.
The hosting provider is Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA — for the European Economic Area, Cloudflare Germany GmbH, c/o Design Offices München Atlas, Rosenheimer Straße 143C, 8th floor, 81671 München, Germany. A data processing agreement pursuant to Art. 28 GDPR is in place with Cloudflare.
Cloudflare operates a globally distributed network, so a request may be served by a server outside the European Union, including in the USA. Cloudflare bases these transfers on the European Commission’s Standard Contractual Clauses.
3.2 Cookies and analytics
This website sets no cookies that are not technically necessary, and embeds no analytics or advertising services, no external fonts and no social networks. Cloudflare may set a technically necessary security cookie in order to fend off automated attacks; it serves that purpose alone and not the analysis of your behaviour.
4. Contact by email
If you write to me, I process your email address and the content of your message in order to answer it. The legal basis is Art. 6(1)(b) GDPR where a contract is involved, otherwise Art. 6(1)(f) GDPR (legitimate interest in answering enquiries). I delete the correspondence as soon as it has been dealt with and no statutory retention periods stand in the way.
The support address is operated at Google (Gmail), Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. If you would rather avoid that, write to me by post at the address given above instead.
From inside the app you can write a support email prefixed with app version, build number, operating system version and language — so that I can pin down bugs. You see this line before sending and can delete it.
5. Your rights
Under the GDPR you have the right to:
- access to the data stored about you (Art. 15)
- rectification of inaccurate data (Art. 16)
- erasure (Art. 17)
- restriction of processing (Art. 18)
- data portability (Art. 20)
- objection to processing based on a legitimate interest (Art. 21) — here this mainly concerns the anonymous usage analytics
For all of this, an email to [email protected] is enough.
A note on access: the data in the app is held exclusively on your device — there you already have all of it in front of you, and I can neither view it nor hand it over. The analytics events are not assigned to any name; in order to be able to assign them, I would need additional information from you that I do not otherwise have (Art. 11 GDPR).
You also have the right to lodge a complaint with a data protection supervisory authority. The one responsible for me is:
Der Hamburgische Beauftragte für Datenschutz und Informationsfreiheit
Ludwig-Erhard-Str. 22, 7th floor, 20459 Hamburg
datenschutz-hamburg.de
