Privacy policy
Last updated: October 14, 2026
Jokerly is made by The Open Apps, Inc., a Delaware corporation ("we", "us"). This policy covers the Jokerly American Mahjong plugin in ChatGPT and the website jokerly.ambientapp.ai. It explains what we collect, why, who receives it, how long we keep it and how you can delete it.
The short version
- Jokerly needs no account. It knows you only by a scrambled form of the anonymous ID that ChatGPT sends.
- The only thing we keep about you is the hands you choose to save from your own mahjong card.
- Your rack, exposures and the tiles you ask about are used to answer you and are not stored on our servers.
- Jokerly never receives your photos: ChatGPT reads them and sends Jokerly tile codes and hand lines.
- Say "Delete my Jokerly card" in ChatGPT and your saved card is deleted at once.
- We don't show ads, sell data, send marketing email, or use analytics or advertising cookies.
What we collect
| What | Where it comes from | Why we need it |
|---|---|---|
| A scrambled (hashed) form of the anonymous user ID that ChatGPT sends | ChatGPT | To keep your saved card for you and nobody else. We never receive your name, email address or chat history |
| The hands you save from your card: each line as you or ChatGPT wrote it, its label and rules (any numbers, concealed), and the card's name | You, through ChatGPT | To check your rack against your own card |
| When you last used Jokerly | Our server | To delete cards nobody has used for 12 months |
| The tiles in each request: your rack, exposures, tiles you've seen, a tile you want to swap | You, through ChatGPT | To answer that request. They are not stored on our servers |
| Technical logs: the time, the page or tool used, the names of the fields sent (not their values), counts, response codes, errors, the approximate country, language and app type ChatGPT reports, and scrambled forms of the user, conversation and workspace IDs ChatGPT sends | Your browser or ChatGPT | To keep the service running and secure and to find problems. Logs never contain tiles, hands, card names or IP addresses |
| Support messages: your email address and message | You | To answer you |
We don't collect names, email addresses (except when you write to support), contacts, photos, precise location or ChatGPT conversations.
About ChatGPT. You use Jokerly through ChatGPT, where OpenAI handles your conversation and any photos you share under OpenAI's privacy policy. ChatGPT reads your photos and sends Jokerly only the tiles and hand lines it read.
How we use it
- To count how many tiles away your rack is from each hand, suggest Charleston passes and check joker swaps.
- To keep the hands you saved, so you don't have to enter your card again.
- To keep the service secure and working, and to answer support requests.
We don't use any of it for advertising, profiling or training AI models, and we never combine your saved card with anyone else's.
Who receives it
| Recipient | What they receive | Why |
|---|---|---|
| OpenAI | Jokerly's answers to your requests, including the tiles and hands they are about, which ChatGPT shows you | So ChatGPT can answer you and show Jokerly's card |
| Hetzner Online GmbH | Our servers and database | Hosting |
Your saved hands are never shown to other users. We may disclose information when the law requires it, or to protect people from harm.
How long we keep it
| Data | How long |
|---|---|
| Your saved card | Until you delete it, or 12 months after you last used Jokerly, whichever comes first |
| The tiles in a request | Not stored on our servers; they stay in your ChatGPT conversation |
| Technical logs | 30 days |
| Support emails | 12 months |
Deleting sooner. Say "Delete my Jokerly card" in ChatGPT, or ask to remove single hands by their number. Deletion is immediate. You can also email support@theopenapps.com.
Children
Jokerly is for ages 13 and up. It is not directed at children under 13. If you think a child under 13 has given us personal data, email support@theopenapps.com and we will delete it.
Your rights
Depending on where you live, you may have the right to access, correct, delete or export your data, or to object to how we use it. Ask Jokerly to show your card ("Show my Jokerly card") to see everything we keep about you, or email support@theopenapps.com and we will answer within 30 days. You can also complain to your local data protection authority.
Cookies
Jokerly and its website set no cookies and use no tracking or analytics.
Security
Connections are encrypted (HTTPS). Your card is stored under a scrambled form of ChatGPT's anonymous ID, made with a secret key that never leaves our server.

We are based in the United States. Our servers are run by Hetzner Online GmbH. OpenAI may process data in the United States and other countries, under its own privacy and security commitments. Cloudflare, Inc. runs DNS for our domain name; our traffic does not pass through Cloudflare.
Changes to this policy
When we change this policy we update the date at the top. If a change affects how we use data we already hold, we will say so on this page before it takes effect.
