Terms of Use

Version 1.0 · 27 July 2026

1. Who provides this

Send a Scratch is operated by DonkeyCat GmbH, Lindengasse 43/19, A-1070 Vienna, Austria. Full details are in the imprint. Using the service means accepting these terms.

2. What the service does

You build a digital scratch card in your browser from an image, some text and optionally a calendar event. Your browser encrypts it, uploads only the ciphertext, and gives you a link to send. Anyone with that link can open the card. There are no accounts and the service is free.

Each card also comes with a manage link, which carries the card id, its key and a five-character code together. It is the only way to check whether a card has been opened, to change it, to reset it or to delete it. We hold neither the key nor the code — only a hash of the code — so we cannot look it up or reissue it. If you lose it, you lose those abilities.

3. What you may not upload

We cannot see what is in a card, and that does not relieve us of the duty to act on reports. Prohibited in particular:

• depictions of child sexual abuse and any sexualised content involving minors;
• content inciting violence or hatred, and National Socialist re-engagement (Verbotsgesetz);
• images of people that violate their rights, in particular intimate images shared without consent;
• third-party copyright, trade marks or trade secrets used without permission;
• phishing, malware, fraudulent vouchers, and use of the service as an anonymous drop for other people's data.

Reports about a specific card are handled using the card id — the part of the link after /k/. Send it to office@donkeycat.com. We cannot inspect the contents, but we can delete the card, and we do when a report is substantiated.

4. How long a card lives

You choose between 7 and 365 days. After that the card deletes itself. Once it has been opened the first time, retention shortens to at most another 14 days, never beyond the original expiry. Anyone holding the management code can delete it sooner.

5. Availability and warranty

The service is provided free of charge and without any guarantee of availability, and may be changed or discontinued. To the extent permitted by law, liability is limited to intent and gross negligence. Nothing here limits liability for injury to life, body or health, or under the Austrian Product Liability Act. Statutory consumer rights are unaffected.

6. Your content

What you put in a card stays yours. You grant us only what is technically necessary to store the ciphertext and serve it to whoever opens the link, for as long as the card lives. You confirm you hold the rights to what you upload.

7. Privacy

What is stored, for how long, and the two things that are deliberately not encrypted are set out in the privacy policy.

8. Governing law

Austrian law applies, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. For consumers, this does not remove the protection of mandatory provisions of the law of their country of residence. The place of jurisdiction for merchants is Vienna.

9. Changes

Material changes are published here with a new version number and date.
