DoOrDonate (the "Service") is operated by Finn Strehl, Kaiser-Friedrich-Ring 142, 40547 Düsseldorf, Germany, trading as Strehl Digital ("we", "us"). These Terms apply to your use of the DoOrDonate mobile app and website.
There are two kinds of contract with us. By creating an account you conclude a user agreement, which is free of charge. Each time you start a challenge, you conclude a separate challenge agreement on the terms shown on the app's review screen immediately before you start.
You commit to a goal — for example three workouts a week for four weeks, or a check on every day of the week — and choose an amount per miss and a charity. Each occasion on which you have committed to do something is a separate required occurrence.
Before you start, the review screen shows the amount per miss, the number of required occurrences, and the most you could ever pay for that challenge (the number of required occurrences multiplied by the amount per miss).
You set up a challenge step by step: goal, schedule and duration (1 to 12 weeks), start date, proof method, amount per miss, charity and card. On the final review screen you see all the terms together and can go back to correct any of them. The challenge agreement is concluded when you confirm the review screen and tap the button that starts the challenge. The app then shows the challenge with its fixed terms.
Once a challenge has started, its terms are fixed: the amount per miss, the schedule, the start date, the duration, the proof method and the charity cannot be changed, by you or by us.
Each challenge keeps the time zone in which it was created. All deadlines are calculated in that time zone, even if you travel.
The amount per miss must lie between the minimum and maximum shown in the app when you create the challenge (currently at least €0.50). We may also limit the total amount you can have at risk across all your challenges within a given period; the app tells you if a challenge would exceed that limit and does not let you start it. If a confirmed miss would nevertheless exceed one of these limits, it is not charged.
You choose one proof method per challenge:
For photo and screenshot proofs you may describe in your own words what the proof will show. That description, together with your goal, is the standard your proof is reviewed against.
Deadlines. You can submit proof for today or for yesterday. Proof for yesterday must arrive by the end of today, in the challenge's time zone. An occurrence for which no accepted proof exists when this window closes counts as a miss.
Review. We review photo and screenshot proofs to check whether they reasonably show that you did what you committed to. If a proof is not accepted, the app tells you, together with the reviewer's note where one is given. While the window for that occurrence is still open, you can submit a new proof. You can also retake a proof that is still waiting for review, as long as its window is open. If an accepted proof is missing when the window closes, the occurrence is a miss.
Automated and AI-assisted review. We may use automated tools, including AI-based image analysis, to help us review photo and screenshot proofs. If a proof is not accepted on the basis of an automated assessment, you can ask for a person to look at it. Every miss can be disputed (section 6), and disputes are always decided by a person.
You must not submit proofs that are misleading, that belong to someone else, or that show other people without their consent. Proofs must not contain unlawful content. We may refuse such proofs.
In the event of a technical outage on our side that prevents timely proof submission, we will extend the applicable deadline and notify affected users by email.
A miss is only confirmed after the proof window has closed. Each confirmed miss has a dispute window of at least three days (72 hours), and nothing is charged before it ends. The app shows when the window for each miss closes.
You can dispute a miss in the app within that window and explain why it should not count, for example because your proof was wrongly rejected or you were prevented by a technical problem on our side. A person reviews every dispute:
Your statutory rights remain unaffected.
Saving a card. Before your first challenge you save a payment card with our payment provider Stripe. Your card details are stored by Stripe, not by us. Saving a card does not charge anything. You authorise the charges described in this section for all challenges you start with that card.
Who you pay. Each confirmed miss is charged to your card as a payment to the charity you chose for that challenge. The charity is the merchant of record. The payment appears on your card statement under the charity's name and is processed within Stripe; the money is not held by us at any time. Charges are made in euros.
What it costs you. You pay exactly the amount per miss for each confirmed miss, nothing more. From each payment, 9% is paid to us as a platform fee to cover the operation of the Service, and the charity pays its own card processing fee out of the rest. No additional fees are added to the amount you pay.
When. A miss is charged after its dispute window has ended, or, if you disputed it, after the dispute has been rejected. Misses are charged individually.
Failed payments. If a charge fails, we may retry it a limited number of times. If your bank requires you to confirm a payment (for example with 3D Secure), the app asks you to do so. A miss is never charged more than once.
Refunds. If a miss was charged in error, for example because it should have been waived, we will arrange a refund. Whether a payment qualifies as a tax-deductible donation, and whether a receipt is issued, is decided by the charity; we make no promise about it.
You can choose from the partner charities listed in the app. Each has its own Stripe account through which it receives payments.
If a selected charity becomes unavailable after your challenge has started, we will forward the donation to an equivalent partner charity and notify you by email within 7 days of settlement.
If you are a consumer, you have a statutory right of withdrawal for each challenge agreement.
Right of withdrawal
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day of the conclusion of the contract.
To exercise the right of withdrawal, you must inform us (Finn Strehl, Strehl Digital, Kaiser-Friedrich-Ring 142, 40547 Düsseldorf, Germany, phone: +49 176 59058049, email: strehldevs@gmail.com) of your decision to withdraw from this contract by an unequivocal statement (e.g. a letter sent by post or an email). You may use the attached model withdrawal form, 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, including the costs of delivery (with the exception of the supplementary costs resulting from your choice of a type of delivery other than the least expensive type of standard delivery offered by us), without undue delay and in any event not later than 14 days from the day on which we are informed about your decision to withdraw from this contract. We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
If you requested to begin the performance of services during the withdrawal period, you shall pay us an amount which is in proportion to what has been provided until you have communicated us your withdrawal from this contract, in comparison with the full coverage of the contract.
Starting before the withdrawal period ends. A challenge starts on the start date you choose when you create it: today, or a later day the app offers. Before you start, the app asks you to expressly request that we begin performing the challenge agreement before the withdrawal period has ended, and to confirm that you know that your right of withdrawal expires once the challenge agreement has been fully performed. If you withdraw, your challenge ends and no further misses arise.
(Complete and return this form only if you wish to withdraw from the contract.)

You can end the user agreement at any time by asking us to delete your account (see Delete your account). From the moment we receive your request, your running challenges end and no new misses arise. Misses that were already confirmed before your request remain payable, subject to your right to dispute them. Records we must keep by law are kept for the statutory period (see our Privacy Policy).
We may end the user agreement with 30 days' notice. We may suspend or end it without notice for good cause, in particular for fraudulent proofs or serious or repeated breaches of these Terms. Where reasonable, we will warn you first. Challenges that are running when we end the agreement end without further misses.
Our liability is unlimited for damage caused intentionally or through gross negligence, for injury to life, body or health, and under the German Product Liability Act.
For damage caused by simple negligence, we are only liable for breaches of an essential contractual obligation (an obligation whose fulfilment makes proper performance of the contract possible in the first place and on whose fulfilment you may regularly rely). In that case our liability is limited to the damage that was foreseeable and typical for this kind of contract when it was concluded.
Any further liability is excluded. These limitations also apply to the personal liability of our employees, representatives and agents.
DoOrDonate is a motivation tool. It does not give medical, fitness or health advice. Choose goals that are safe for you.
The terms of a challenge that has already started never change. We may change these Terms for future challenges and for the user agreement if there is a valid reason, such as a change in the law or a new feature. We will tell you about changes in the app or by email before they take effect, and ask you to accept them. Changes do not apply to you unless you accept them. If you do not accept them, you can keep using the Service for your running challenges, and we may end the user agreement with notice under section 10.
Contracts are concluded in English. A German translation of these Terms is provided for convenience. These Terms can be viewed and saved at any time at this address. The terms of each challenge are stored by us and remain visible in the app on the challenge's detail page.
Main characteristics: Personal accountability challenges in which each missed occurrence costs an amount per miss you choose, paid to a charity you choose; proof by photo, screenshot, GPS check-in or your own confirmation; review of photo and screenshot proofs; a dispute window before any charge.
Price: The account and challenges are free. You pay only the amount per miss for each confirmed miss. The maximum for each challenge is shown before you start it. There are no further fees, delivery costs or subscriptions. We apply the small-business rule under § 19 UStG and therefore do not charge VAT.
Duration: Each challenge agreement runs for the duration you choose (1 to 12 weeks) and ends when its schedule has run out and its last miss has been decided. The user agreement runs indefinitely until it is ended under section 10.
Technical requirements: An Android or iOS device with an internet connection. Photo proofs need camera access, GPS check-ins need location access, and screenshot proofs need access to the images you select.
We are neither willing nor obligated to participate in dispute resolution proceedings before a consumer arbitration board. Please contact us directly at strehldevs@gmail.com — we aim to resolve every issue amicably.
These Terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer resident in another EU member state, the mandatory consumer protection provisions of that state continue to apply. The exclusive place of jurisdiction for disputes with merchants is Düsseldorf, Germany.
If any provision of these Terms is invalid, the rest of the Terms remain valid.
