Privacy Policy
Last updated: October 16, 2026
The short version. We collect only what we need to run your bridge practice. We do not sell your information, we do not show ads, and we do not use tracking or advertising cookies. The text of your practice sessions is sent to Anthropic, which provides the AI tutor, and payments are handled by Stripe.
1. Who we are
BridgeBidder.com is operated by Dennis G. Douglas, a sole proprietor in Bend, Oregon, USA, doing business as BridgeBidder. We decide how your personal information is used (in some countries' terms, we are the "controller"). Contact: support@bridgebidder.com.
This policy is part of our Terms of Service.
2. What we collect
| Information | Where it comes from | Why we need it |
|---|---|---|
| Your email address and first name, if you join the "notify me" list | You, through the sign-up form | To tell you when BridgeBidder opens |
| Name, email address and (for players aged 13 to 17) a parent's or guardian's email address | You, when you create an account or buy hands | To run your account, send receipts and important notices, and answer support requests |
| Purchase records: what you bought, when, the amount, your country, and the card type and last four digits | Stripe | To give you your hands, handle refunds and keep the records tax law requires |
| Your practice sessions: the conventions you chose, the hands dealt, your calls, the tutor's explanations and anything you type to the tutor | Your use of the Service | To run the tutor, let you resume sessions and print hands, show your score, and find and fix problems |
| Technical information: IP address, browser type, and the time and pages of your visits | Your browser, recorded automatically by our host | To keep the site working and secure and to prevent abuse, such as repeated free-hand sign-ups |
| Messages you send us | You, by email | To answer you |
We do not receive or store your full card number; Stripe handles that. Please do not type personal or sensitive information into the tutor. It only needs your bids and bridge questions.
3. Who processes it for us
We use a small number of companies to run the Service. They may handle your information only to provide their services to us.
- Anthropic provides the AI model (Claude) behind the tutor. To produce each reply, the text of your session is sent to Anthropic, which processes it under its commercial terms and privacy policy.
- Stripe processes payments. It receives your payment details directly and handles them under its own privacy policy.
- Netlify hosts the website and receives the "notify me" sign-up form.
- Our server and email providers run the practice service and our support@bridgebidder.com mailbox.
We may also disclose information if the law requires it, to protect the Service or its users from fraud or abuse, or to a buyer if the business is ever sold (in which case this policy will continue to apply).
We do not sell or rent your personal information, and we do not share it for advertising.
4. Cookies and browser storage
We do not use advertising or tracking cookies. The practice page stores two small items in your own browser: your access key, so you stay signed in, and your sound on/off setting. You can clear them at any time through your browser's settings; you will then need to enter your key again.
5. How long we keep it
- "Notify me" list: until we have sent the opening announcement, or until you unsubscribe, whichever comes first. If you then create an account, your account details are kept as described next.
- Account details and practice sessions: while your account is open. If you ask us to delete your account, we delete these within 30 days.
- Purchase records: as long as tax and accounting laws require, usually up to seven years.
- Technical logs: for a limited period, normally no more than 90 days, unless needed to investigate abuse or a security problem.
6. Young players
BridgeBidder is not for children under 13, and we do not knowingly collect personal information from them. Players aged 13 to 17 may use the Service with a parent's or guardian's permission, and the parent or guardian makes any purchases. If you believe a child under 13 has given us information, email us and we will delete it.
7. Your choices and rights
Wherever you live, you can email support@bridgebidder.com to:
- get a copy of the personal information we hold about you;
- correct anything that is wrong;
- delete your account and practice records (we will confirm within 30 days);
- unsubscribe from our emails (every marketing email also has an unsubscribe link).
We may need to confirm your identity first, usually by replying from the email address on your account. We will not treat you differently for using these rights.
If you live in the European Economic Area, the United Kingdom or Switzerland, you also have the right to object to or restrict our use of your information, to receive it in a portable format, and to complain to your local data protection authority. Our legal bases are: performing our contract with you (running your account and sessions); our legitimate interests (keeping the Service secure, preventing abuse and improving it); your consent (the "notify me" list, which you can withdraw at any time); and legal obligations (tax records).
If you live in a U.S. state with a privacy law, such as California or Oregon, you have the rights described above, and we do not sell or share personal information for targeted advertising.
8. International transfers
BridgeBidder is run from the United States, and our providers process information in the United States and possibly other countries. If you use the Service from elsewhere, your information will be transferred to the United States, where privacy laws may differ from yours. Where the law requires, we rely on our providers' standard contractual safeguards for these transfers.
9. Security
We use reasonable safeguards, including encrypted (https) connections and limited access to our systems. No service can promise perfect security. If a breach affects your information, we will tell you as the law requires.
10. Changes to this policy
We may update this policy. The date at the top shows the latest version. For material changes, we will email account holders at least 30 days before they take effect.
