This policy explains what Happy Cactus Games ("we") collects when you use Shogi King, why, who else sees it, and what you can do about it. Questions or requests: [contact email not configured].
1. What we collect
| What | Why | Kept for |
|---|---|---|
| Username, email address, password (stored only as a salted hash) | Your account, logging in, account emails | Until you delete your account |
| Your games: moves, times, results, ratings, chat messages | Running the game; game review, the opening explorer, puzzles and statistics | Games are kept as part of the public record (see below) |
| Puzzle attempts, review unlocks, puzzle lives | The puzzle map and the free-tier allowances | Until you delete your account |
| Subscription status and a Stripe customer reference | Knowing whether you have Premium | As long as needed for tax and accounting law (usually 7 years), then deleted |
| IP address, browser user-agent, request logs | Security, rate limiting, abuse prevention, fixing faults | Up to 90 days |
We don't sell your personal information, and we don't use it for anything other than running the site as described here.
2. What is public
Your username, rating, record and games are visible to everyone, and games can be downloaded and reviewed by anyone. Your email address, puzzle history, billing details and personal statistics insights are not public.
Follows, activity and presence
Follows are one-way and public on your profile only as two counts (followers and following); the lists are visible to you. Blocks are private: the blocked player is not told. A block removes follows both ways, cancels pending challenges, and stops reactions, challenges, activity and online status passing between you.
Activity — daily tsume solves, finished games, rating and streak milestones, completed puzzle packs and Tsume Rush bests — is shown to your followers by default. You can limit it to people you follow back, or turn it off, in social settings; the change applies to past items immediately. Activity items are deleted after 90 days.
Online status ("online", or "playing" with a link to watch) is shown by default only to people you follow who follow you back, and can be turned off. It is computed from your open tabs and kept for 90 seconds after your last one closes; it is not stored.
Notifications (follows, challenges) are kept for 30 days. Reactions in games are a fixed list of sayings, sent live and never stored.
Daily tsume: if you play logged out, your streak is kept only in your browser's local storage; when you sign up we copy up to 60 days of it (checked against real puzzle numbers) into your account.
3. Payments
Payments are handled by Stripe. Your card details go to Stripe directly and never reach our servers. Stripe tells us whether a payment succeeded and gives us a customer reference, which we store to link your subscription to your account.
4. Cookies and local storage
- Session cookie (
session) — keeps you logged in. Strictly necessary; it expires after 7 days. - Local storage — remembers display preferences such as the piece set and board options on your device, a logged-out daily tsume streak and lesson progress. Preferences are never sent to us; the streak and lesson ticks are copied into your account when you sign up.
5. Ads
The site doesn't currently show third-party ads. If that changes, this section will say which provider is used and how to control it, and you'll be asked for consent where the law requires it.
6. Who else processes your data
- Stripe — payments.
- Our hosting and network providers — to run the servers.
- Authorities — only when the law requires us to.
7. Your rights
You can ask us to give you a copy of your data, correct it, or delete your account. Email [contact email not configured] from the address on your account. When you delete your account we remove your email, password and private records; your past games remain part of other players' histories but are shown under an anonymous name. Depending on where you live (for example the EU, the UK or California) you may have further rights, including to complain to a data protection authority. We answer requests within 30 days.
8. Children
The site is not directed at children under 13 and we don't knowingly collect their data. If you believe a child under 13 has an account, contact us and we'll remove it.
9. Changes
If we change this policy in a way that matters, we'll say so on the site before it takes effect. The date at the top shows when it last changed.
