Privacy policy
This is a small informational website for a volunteer-run non-profit judo club. We don't ask for your data, and we don't sell it.
In plain English: This website has no accounts, no forms, no newsletter, no shopping cart, no analytics and no advertising. The Google map stays off until you allow it. If you sign up for classes, that happens on the City of Petaluma Parks & Recreation system, not here, and their privacy policy governs it.
1. Who we are
DeLeon Judo Club (“the Club,” “we,” “us”) is a 501(c)(3) non-profit organization based in Petaluma, California, operating in partnership with the City of Petaluma Parks & Recreation Department. This policy covers this website and the information the Club handles. It does not cover the City of Petaluma, our registration provider, or any other organization we link to.
The Club is the data controller for that information, which means we decide why and how it is used. You can reach us using the details in section 15.
2. Information we collect
This site is a set of static pages. We do not operate accounts, logins, contact forms, mailing lists, e-commerce, or advertising on it. You can use the whole site without giving us any personal information. Specifically:
- We do not ask you for personal information on this website. There is no form to fill out.
- We do not set our own cookies, and we do not use analytics or advertising trackers.
- Your browser remembers your map choice. It is kept in your browser's local storage under the name djw-consent and is never sent to us. Our Cookie Policy has the details.
- Our web host may keep standard server logs — the kind every web server keeps, such as IP address, browser type, pages requested, and date and time. These are generated automatically by hosting infrastructure, used for security and to keep the site running, and are not used by us to identify individual visitors.
3. Information you send us voluntarily
This website does not publish instructors' personal phone numbers or email addresses. It only offers a shared club email address. If you speak to an instructor at the dojo or write to us, we will have whatever you choose to tell us — typically your name, a way to reach you, and information about the student who wants to train. We use that information only to answer you and to help you get started at the club. We do not add you to any marketing list, and we do not sell, rent, or trade it.
4. Third-party services on this site
Three outside parties are involved when you use this website:
- Our web host. It delivers these pages to your browser and may keep the server logs described in section 2.
- Google Maps. A map appears on our home, classes and contact pages. It stays blocked until you choose “Allow maps” in the banner or “Show map” on the map. Only then does your browser contact Google, which may receive your IP address and set cookies under its own privacy policy. If you choose “No thanks,” the map does not load and the rest of the page works as normal. Our “Get directions” links take you to Google Maps on Google's own site.
- Petaluma Parks & Recreation registration (rec1.com). Our “Register” links take you off this site to the City of Petaluma's registration catalog. Any name, contact, payment, or health information you enter there is collected and held by the City and its registration provider, under their policies — not ours. We never see or store payment card information.
We do not control Google or the City's registration provider and are not responsible for their practices. Please review their privacy policies directly.
5. Children's privacy
We teach students ages 6 and up, so children are an important part of our club — but this website is written for parents and adults, and it is not directed at children as an online service. In keeping with the US Children's Online Privacy Protection Act (COPPA), we do not knowingly collect personal information from anyone under 13 through this website. Enrollment for a minor is completed by a parent or guardian through Petaluma Parks & Recreation. Allowing the map is a choice for a parent or guardian to make. If you believe a child has sent us personal information, contact us and we will delete it.
6. Photographs and video
Photographs taken at the dojo, at tournaments, or at club events may appear on this website or on club materials. If you or your child appears in a photograph you would like removed, tell any instructor and we will take it down. Students and parents may also tell any instructor at any time that they prefer not to be photographed, and we will honor that.
7. How we use and share information
We use the limited information described above to respond to inquiries, run classes, and administer club membership and rank certification. We may share a student's name, rank, and membership details with the organizations that certify our members — the United States Judo Federation (USJF), our yudanshakai the Central Coast Judo Association (CENCO), and USA Judo — for the purposes of promotion records, insurance, and tournament entry. We share information with the City of Petaluma as needed to administer the program. Beyond that, we do not disclose personal information except where required by law. We do not use personal information for profiling or automated decisions.
8. Legal bases
Where the GDPR or a similar law applies, these are our legal grounds for using personal information:
- Legitimate interests. We rely on this for server logs, which keep the site secure and running, and for club administration: answering you, running classes, keeping membership and rank records, and the photographs described in section 6.
- Consent. We rely on this for the Google map. You can withdraw it at any time through “Cookie settings” in the footer or on our Cookie Policy page.
- Legal obligation. We rely on this where the law requires us to keep or disclose something.
9. International transfers
The Club operates in the United States, so information we hold is handled here. If you allow the map, your browser sends information to Google, which may process it in the United States. Our web host may also process server logs in the United States or elsewhere. US privacy law may give you less protection than the law where you live. Google describes how it handles transfers in its privacy policy.
10. Security and retention
We keep club records only as long as needed for club administration, rank records, and legal or insurance requirements. Server logs are kept by our web host under its normal practice. Your map choice stays in your browser until you change it or clear it. No website or method of storage is perfectly secure, and we cannot guarantee absolute security of information transmitted over the internet.
11. Your choices and rights
We are a US club and we don't target people in the EU or UK, so the GDPR may not apply to us. We extend these rights to anyone, wherever you live:
- Access. Ask what we hold about you and get a copy.
- Rectification. Ask us to correct anything that's wrong.
- Erasure. Ask us to delete your information.
- Restriction. Ask us to limit how we use it.
- Objection. Object to any use based on our legitimate interests.
- Portability. Ask for the information you gave us in a common format.
- Withdrawing consent. Change your map choice at any time through “Cookie settings.”
- Complaint. Complain to the data protection supervisory authority where you live or work.
To review or change your information, or to use any of these rights, contact us using the details in section 15. A parent or guardian can ask on behalf of a child. We may ask you to confirm who you are, and we may need to keep some records for legal or insurance reasons. If so, we will tell you. Information held by Google or the City is theirs to manage, so please ask them directly.
12. California privacy law
The California Consumer Privacy Act (CCPA) applies to for-profit businesses. The Club is a non-profit, so it is not covered. Even so, we do not sell or share personal information as the CCPA defines those terms.
13. Do Not Track
This site does not track visitors across other websites, so it does not respond differently to Do Not Track browser signals. If you allow the map, Google's own policy covers what it does.
14. Changes to this policy
If we change this policy, we will post the new version on this page and update the “Last updated” date at the top. This website has no mailing list, so we can't notify you directly. The new version applies from that date.
15. How to reach us
Questions about this policy, or a request about your information, can reach us in person at the dojo.
