Terms of service
Updated 26 July 2026
Sankki is an online version of the Shanghai contract rummy card game, provided by HD-SofT Oy. By using the service you accept these terms.
Account
You sign in with an emailed link. You are responsible for the email address being yours and for not passing the sign-in link on. One account is for one person.
Subscriptions and prices
A personal subscription is €2.99/month and a group subscription €5.99/month (the payer + 5 members). In the app stores the price is shown in your local currency and Apple or Google is the seller. Your first started game is free; after that playing requires your own subscription or membership in a paid group.
A subscription renews monthly until cancelled, and a cancelled subscription stays active until the paid period ends. A subscription bought in the browser is cancelled in your Profile; one bought in an app store is cancelled in that store’s own subscription settings — we cannot cancel it for you.
Refunds
The 14-day right of withdrawal for digital services lapses once you have consented to the service beginning. Subscriptions bought in an app store are refunded under that store’s rules. For a clearly incorrect charge, contact info@sankki.app.
Playing and conduct
Play honestly. Verbal harassment is not possible here, because table talk consists of ready-made phrases. Automated play, interfering with the service and using someone else’s account are forbidden, and we may close an account for such breaches.
Availability
We do our best, but the service is provided as it is: we do not guarantee uninterrupted operation, and maintenance can interrupt a game in progress. We are not liable for indirect damage, and our liability is limited to the fees you paid during the last 12 months.
Changes and governing law
We may change these terms and the prices by announcing it in the app at least 30 days in advance; continuing to use the service after the change means accepting it. Finnish law applies, and disputes are heard by the District Court of Helsinki or the Consumer Disputes Board. Contact: info@sankki.app.
