Terms of Use

Last updated: 20 October 2026

This translation is provided for convenience. Only the German version is legally binding.

1. Provider and scope

Abmarsch is provided by eastfreak Studios, owner Steffen Kilian, Semperstraße 3d, 01069 Dresden, Germany. Contact: kontakt@abmarsch.app.

These terms apply to the use of the Abmarsch app (phone, watch, widget) – free and with Abmarsch Plus. You buy Abmarsch Plus from the store (section 7); the store's terms apply to that purchase in addition. How we handle your data is described in the privacy policy.

2. What Abmarsch is

Abmarsch helps you leave and arrive on time: the app calculates backwards from your destination, wakes and reminds you, raises an alarm and shows your time buffer. With Abmarsch Plus, up to 6 people can connect as a family, suggest appointments to each other, agree on times and – only if the other person shares an appointment with them and only during that appointment – see its status or location. A watch app (Wear OS) and a widget are part of the app.

3. What Abmarsch is not

Abmarsch is not an emergency or safety service and does not replace supervision. Wake-up calls, alarms and notifications may not arrive or may be delayed, for example without network, with an empty battery, with location switched off, battery saving or restrictions of the operating system.
Timetable and real-time data (departures, delays, cancellations, platforms) come from third parties (DELFI e.V., gtfs.de). We pass it on as we receive it and cannot guarantee that it is correct. If in doubt, check the information of the transport operator.
Times, buffers and learning suggestions are estimates. We do not guarantee that you will arrive on time. We are only liable for the consequences of being late (e.g. missed lessons, appointments or connections) under section 12.

4. The leave alarm

The leave alarm is deliberately persistent: it only ends when the app detects that you have left (leaving the start area and moving), when you call off the appointment with a reason (e.g. sick, appointment cancelled), or automatically 60 minutes after the departure time; the appointment then counts as missed. There is no button that ends it without movement. If you are under 16 and in a family with Abmarsch Plus, the app asks the family's adult admins before you call it off; until one of them answers, the alarm comes back every 3 minutes. If there is no adult admin in the family or the family is paused (section 6), the reason is enough. From 16 you call it off yourself; whoever the appointment is shared with is told.

For the alarm to work, the app needs the permissions for location, motion, notifications and alarms. Without them Abmarsch cannot warn you reliably.

5. Account, family and age

The app is fully usable without an account; your data then stays on your device. You only need an account for the family (with Abmarsch Plus, section 6) and so that a subscription applies to the family.
You are responsible for the information in your profile and keep your sign-in secret.
A family has members and admins. Whoever founds the family is an admin; admins invite and remove members, rename the family and make others admins. Labels such as "Papa" or "Oma" are only names and carry no rights.
Minors use Abmarsch with their parents' agreement. When you join a family, you enter your birth year; it must be correct. Under 16 you share nothing in the family until an admin of the family who is of age has consented (privacy policy, section 7).
Anyone who consents for a member under 16 must be of age (at least 18) and have parental responsibility for the child or be authorised by the persons who have it.
Every member decides which of their own appointments to share with whom. Nobody changes another member's appointments, times or sharing directly, only as a suggestion or request that this member confirms. Sharing only happens during an appointment and is always visible on the device of whoever shares.
Every member can leave the family at any time.

6. Free and Abmarsch Plus

Abmarsch is available for free for one person and with the Abmarsch Plus subscription. There is no other paid plan.

Free: one active repeating appointment (you can save and swap more; one-off appointments do not count), wake-up alarm, leave alarm, live buffer, detour warning, learning suggestions, timetable without real-time data, statistics for the last 7 days, streaks and badges, widget, weather and watch app. On the free plan you use Abmarsch on your own; the family is only available with Plus.
Abmarsch Plus in addition: any number of active appointments, real-time data for bus and train (delay, cancellation, platform), full statistics history and the family of up to 6 people: connecting phones, sharing appointments, appointment suggestions, agreements and change requests, status messages (e.g. left, arrived, not left, missed the train), live map (end-to-end encrypted) and nudges.
For the whole family: If one member pays for Plus, all members of every family that member belongs to have Plus. One subscription in the family is enough: anyone who is invited (e.g. a child) needs no subscription of their own to join and use the family.
When Plus ends: If the paying member leaves the family or their subscription ends and nobody else in the family has Plus, the family stays but is paused: nothing is shared any more, not even status; new agreements, proposals and change requests as well as nudges are not possible. Appointments, alarms and data on the devices stay, nothing is deleted. Members under 16 then call off an appointment with a reason on their own, without asking the admins. When Plus comes back, the family continues as before, without having to agree on anything again.
Prices: currently €4.99 per month or €39.99 per year. The final price the store shows you before the purchase is binding.
7 days free: New subscribers can try Plus for free for 7 days where the store offers it. If you cancel before the trial ends, you pay nothing. Otherwise the paid subscription starts afterwards.

7. Purchase, renewal and cancellation of Plus

The store is your contracting party for the purchase: You buy Plus via Google Play or the App Store. In the EU and the EEA you conclude the purchase contract with the store operator – for Google Play with Google Commerce Limited (Ireland), for the App Store with Apple Distribution International Ltd. (Ireland). The store collects the price, issues the invoice and is responsible for payment and refunds; its terms apply in addition. We provide the Plus features in the app under these terms.
In Switzerland Google Play sells on our behalf: there you conclude the purchase contract with us; Google collects the price for us and handles refunds under its policies.
The subscription renews automatically for the selected term (month or year) unless you cancel it beforehand.
You can cancel at any time in the store's subscription settings (Google Play: Profile → Payments & subscriptions → Subscriptions; iPhone: Settings → your name → Subscriptions) or in the app on the plans page via "Manage subscription". Cancellation takes effect at the end of the paid period unless the store provides otherwise. Deleting the app or your account does not cancel the subscription.
When the subscription ends, no data is deleted: additional repeating appointments are paused (you choose which one stays active), the family is paused (section 6), and Plus features are switched off.

8. Right of withdrawal for purchases

As a consumer in the EU or the EEA you have a statutory right of withdrawal of 14 days when you buy Plus. Because you conclude the purchase contract with the store (section 7), you declare the withdrawal to the store, and the store refunds the price:

Google Play: to Google Commerce Limited, as described in the Google Play Terms of Service (e.g. via the order history of your Google account or Google Play support).
App Store: to Apple, as described in the Apple Media Services Terms and Conditions (e.g. via reportaproblem.apple.com).

You receive the withdrawal information and the model withdrawal form from the store. In Switzerland there is no statutory right of withdrawal for such purchases; refunds there follow Google Play's policies. We cannot refund payments ourselves because we do not receive them. Still, feel free to write to kontakt@abmarsch.app if something goes wrong – we will help you.

9. Updates and defects

We keep Abmarsch working and secure and provide updates for this as long as we offer the app. Please install them promptly; some features no longer work with outdated versions.
If something does not work as described, write to kontakt@abmarsch.app or use "Report a problem" in the app. Your statutory rights in the event of defects (in particular §§ 327 et seq. of the German Civil Code) remain unaffected; for Plus they exist against your contracting party under section 7, and we will support you.

10. Changes to the app

We keep developing Abmarsch. We only change features for a valid reason – for example new operating system versions, security, changes in the law or in data sources, or to improve the app – and at no extra cost to you. If a change impairs the use of Plus more than insignificantly, we will inform you clearly in advance; you can then end your subscription under the statutory rules (§ 327r of the German Civil Code). Servers may be briefly unavailable for maintenance; wake-up alarm, leave alarm and buffer then continue on the device with the data last loaded.

11. Fair use

It is prohibited to use Abmarsch to locate or monitor people without their knowledge, to add other people to a family against their will, to use nudges for harassment, to query the timetable server automatically or to manipulate the app technically. In case of a violation we may block your account, as a rule only after a warning; in serious cases (e.g. secretly locating a person) immediately. Your data on the device and your rights from a paid subscription remain unaffected.

12. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, for fraudulently concealed defects, under a guarantee we have given and under the German Product Liability Act. In cases of slight negligence we are only liable for breach of essential contractual obligations (obligations whose fulfilment makes use of the app possible in the first place and on whose compliance you may regularly rely), and then limited to the foreseeable damage typical for the contract. Otherwise we are not liable for slight negligence. These rules also apply to the people we use to perform our obligations.

13. Term and end of use

You can stop using Abmarsch at any time: delete the app and, if you have an account, delete the account (in the app under "Profile → My data" or at abmarsch.app/konto-loeschen). You cancel a running subscription separately in the store (section 7).
We can end the free use and your account with two months' notice; for good cause (e.g. a serious violation under section 11) also without notice.
If we discontinue Abmarsch altogether, we will announce it in the app at least three months in advance. For periods already paid in which you can no longer use Plus, you will get the pro-rata price back.

14. Changes to these terms

If we change these terms, we will show you the new version in the app in good time beforehand. Changes that are solely to your advantage or purely linguistic apply from publication. For all other changes we ask for your consent; without it, the previous terms continue to apply to you. We may then end the free use under section 13; a paid subscription continues on the previous terms until the end of the paid period.

15. Governing law and dispute resolution

German law applies. If you live in another country as a consumer, you keep the protection of the mandatory consumer protection provisions of your country. We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.
