Terms of Use Wheelcrew

As of: 2 November 2026. English translation; the German version is binding, see section 14.

What has changed since the version of 27 October 2026:

“Booking” instead of “reservation”: we now use the term “booking”; this does not change anything in substance.

Test features: we may first enable individual features only for selected groups as test features (section 9). Cost sharing is currently only available as a test feature (sections 2 and 6).

Withdrawal: if you bought a subscription via Google Play or the App Store, you can also declare your withdrawal via the store's refund function (section 8).

Clarification: members are themselves responsible for insurance, taxes and their agreement on use (section 2).

Export: in groups with cost sharing, members can export their own data and admins the group's data in the app (section 6).

1. Who we are and what these terms cover

Wheelcrew is provided by Adrian Bürkner (trade name: AJ-Dev), Nonnenstraße 11, 04229 Leipzig, Germany (email: adjadevelop@gmail.com). These terms apply to your use of the Wheelcrew app (Android, iOS, web view) in the Free, Pro and Expert plans. Wheelcrew is intended for people aged 16 and over. If you are under 18, you may only enter into a subscription with the consent of your legal representatives.

2. What Wheelcrew does

Wheelcrew helps groups coordinate shared vehicles: location when parked, bookings (reservations), key locations, blocked times, activity log, statistics and – depending on the plan – tasks and messages; cost sharing is currently only available to selected groups as a test feature (section 9). The app shows which functions belong to which plan before you buy. Wheelcrew is a coordination aid. It does not replace checking a driving licence, insurance or the condition of a vehicle, nor a locking system. Members are themselves responsible for insurance, taxes and their agreement on use.

Admins can set the maximum length of a booking. Weekly series are created by the app as individual bookings, at most twelve; each can be changed or cancelled individually.

3. Account, groups and roles

You can use Wheelcrew anonymously with a user ID, or with an email address, Google or Apple. A group is managed by admins; they can invite members, assign roles, change settings and view entries. Anyone who knows a group's join code can join. Share codes and invitations only with people to whom you want to show the group's information. The plan applies to the group (see section 6).

If you use Wheelcrew for an association, a company or a similar organisation, you are responsible for ensuring that the organisation complies with data protection and co-determination rules towards its members or employees. We conclude the data processing agreement under Art. 28 GDPR on request; we offer it for groups in the Expert plan.

4. Rules for content

You are responsible for what you enter. Please enter only true information that you may show to the group. Not permitted are unlawful, insulting or discriminatory content, information about third parties without their consent, health or other particularly sensitive information, access data for accounts and codes that you would not entrust to all members of the group (lock codes are readable by all members and stored in plain text), and using location and activity data for purposes outside the group, such as monitoring individual persons. Do not misuse Wheelcrew, do not disrupt its operation and do not try to bypass safeguards or retrieve other groups' data.

Your content remains yours. You allow us to store it and display it in your group to the extent necessary to operate Wheelcrew.

5. Reports and measures

You can report unlawful content to us by email as described in the legal notice; in the app you can use "Feedback to the developer" in the settings, which opens your email program. We review reports and decide in line with the legal requirements. If content breaches these terms or the law, we may remove content, remove a member from a group or suspend an account. We prefer milder means, such as a warning, unless the breach is serious. We decide after personal review and do not use automated procedures for this. If we remove content or suspend an account, we will tell you what we did, on which facts and legal basis the decision rests and what options you have to challenge it: a complaint to adjadevelop@gmail.com, which we will review again in person, a complaint to a supervisory authority, and recourse to the courts.

6. Pro and Expert subscriptions

The Pro and Expert plans are subscriptions. You buy them only through Google Play or the Apple App Store. The parties to the subscription are you and us; the store handles payment, billing and taxes as the selling party on our behalf under its own terms, and its rules on refunds apply in addition; you can also contact the store directly about refunds. The store shows the price, billing period (monthly or yearly), term and tax notices before you buy. We do not receive payment data. The subscription runs for the chosen billing period and then renews for an indefinite period as long as you do not end it; after the first term you can end it at any time with one month's notice.

The plan applies to a group, not to an individual person: whoever buys the subscription activates it for the group in which they buy it, and all members of that group can use the functions. Members who did not buy do not thereby enter into a contract with us of their own and have no claim that the buyer continues the subscription. When the subscription ends, the group falls back to the free plan (to Pro when switching from Expert to Pro). The group's data remains stored and is not deleted; functions that are only included in higher plans (for example tasks, message templates and the group log) are then no longer available. Vehicles and members already created beyond the limits of the plan remain; you cannot add more. In groups with cost sharing, members can export their own cost-sharing and usage data and admins can export the group's data in the app; otherwise, on your request we will provide you with the stored data concerning you.

You end a subscription in the subscription settings of Google Play or the App Store. You can also give notice to us informally by email to adjadevelop@gmail.com; we will confirm receipt and the end of the contract in text form. In any case you also end the charging in the store, because that is where the payment runs. Deleting your account or leaving a group does not end a subscription; cancel it in the store first. Any member can buy a subscription for the group. If several members buy, several subscriptions arise, each of which must be ended in the store; the app currently does not warn about a double purchase. If the buyer leaves the group, their subscription continues for the group until they end it in the store. We change terms and prices for running subscriptions only if the store obtains your consent or the law permits it.

7. Tips

Tips are voluntary contributions that you make as a one-off purchase through the store. They do not unlock any function and give rise to no claim to anything in return. Whether a right of withdrawal exists and how a refund works depends on the store's rules and your statutory rights.

8. Right of withdrawal for consumers

For subscriptions we are your contracting party (section 6). The following applies.

Withdrawal instructions

You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day of conclusion of the contract. To exercise your right of withdrawal, you must inform us (Adrian Bürkner, AJ-Dev, Nonnenstraße 11, 04229 Leipzig, Germany, email: adjadevelop@gmail.com) of your decision to withdraw from this contract by an unequivocal statement (for example by email). You may use the model withdrawal form below, but it is not obligatory. To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we shall reimburse to you all payments received from you without undue delay and in any event not later than fourteen days from the day on which we are informed about your decision to withdraw. The refund is made through the store and using the same means of payment as you used for the purchase; you will not incur any fees as a result. If you requested that the service begin during the withdrawal period, you shall pay us an amount which is in proportion to what has been provided until you have communicated to us your withdrawal, in comparison with the full coverage of the contract.

Early expiry

The right of withdrawal expires if we have fully provided the service and began performance only after you expressly consented and acknowledged that you lose your right of withdrawal once the contract has been fully performed.

Model withdrawal form

If you want to withdraw from the contract, write to us: "I/We hereby give notice that I/We withdraw from my/our contract for the purchase of the following digital service: [plan and group]. Ordered on: [date]. Name of the consumer(s): [name]. Address: [address]. Date, signature (only if notified on paper)."

If you bought via Google Play or the App Store, you can also declare your withdrawal via the store's refund function or by e-mail to us; we confirm receipt by e-mail.

9. Availability, updates and defects

We strive for uninterrupted operation. Disruptions of the services used (Google, Apple, Expo, RevenueCat) may affect it; your statutory rights remain unaffected. We announce maintenance where possible. We provide the updates that are necessary to keep the product in conformity. We may change functions for a valid reason, such as security, a change in the law, requirements of Google, Apple or the services used, or technical development. This does not cause you additional costs. We inform you beforehand in a clear and comprehensible manner in the app and, where we have your email address, by email. If a change affects your use by more than a minor degree, you can end the subscription free of charge within 30 days after the information or, if later, after the change (Section 327r German Civil Code). We may first enable individual features only for selected groups as test features. Test features may contain errors and may be changed or removed; we point this out in the app. Your statutory rights in case of defects of digital products (Sections 327 et seq. German Civil Code) remain unaffected.

10. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body and health, for fraudulently concealed defects, for guarantees given and under the Product Liability Act. In case of slightly negligent breach of an obligation that is essential for achieving the purpose of the contract (cardinal obligation), our liability is limited to the foreseeable damage typical for this type of contract. Otherwise we are not liable for slight negligence. Liability under the provisions of the General Data Protection Regulation remains unaffected.

11. Relationship between members

Wheelcrew organises coordination within a group, but we are not a party to the arrangements between members. Whoever uses a vehicle, shares costs or hands over a key does so on the basis of their arrangements with the group. Location, key and billing information comes from the members; we do not check it and give no assurance that a vehicle is at the displayed place or a key is at the stated place. Cost sharing is a calculation aid and not legal or tax advice; it does not process payments. The rules for cost sharing are set by the group's admins.

12. Term and termination

You can stop using Wheelcrew at any time and delete your account in the app. We can end free use with 30 days' notice, and for good cause, such as serious misuse, with immediate effect. You end a subscription in the store as described in section 6. If we end the use of a group in the Pro or Expert plan without good cause, we refund fees already paid proportionately for the time after the termination.

13. Changes to these terms

Changes to these terms take effect only with your consent. We notify you in the app at least 30 days beforehand and obtain your consent there. If you do not consent, the previous terms continue to apply to you; we may then end use under section 12 if continuing on the previous terms is unreasonable for us. Continued use alone does not count as consent.

14. Final provisions

German law applies. Mandatory consumer protection provisions of the state in which you have your habitual residence remain unaffected. The statutory places of jurisdiction apply to disputes. We do not take part in dispute resolution proceedings before a consumer arbitration board. The contract language is German; this English version is a translation for information, and in case of discrepancies the German version prevails. We do not store the contract text for you; you can access these terms at any time on the legal pages linked in the app and in the store listings, and save them as a PDF file. You can correct input errors in purchase data before completing the purchase in the store. Should a provision be invalid, the remainder remains effective.
