Sleep Buddy is run by Zhengtao Long, operating as ChowChow Labs (Ontario, Canada). This policy explains how we handle your personal information, in line with Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA). Questions: chowchowbuy@gmail.com.
Sounds, timers and alarms
Every sound is generated in your browser. Your sleep timers, alarms, colour theme, volume and last soundscape are kept in your browser’s storage on this device and are not sent to us. Clearing your browser’s site data removes them.
What we collect
- Your email address, if you create an account, to sign you in and send sign-in codes. Accounts are stored in the same database as our other ChowChow Labs websites, but each site keeps its own membership and its own subscription.
- Your saved mixes (names, icons, sounds and volumes), if you’re signed in, so they’re available on every device you use.
- Subscription status: whether you have Premium, when it renews or ends, and Paddle’s customer and subscription IDs. We never see or store your card or PayPal details.
- Basic technical logs (such as IP address, browser and error messages), kept briefly by our hosting provider for security and troubleshooting.
Who helps us run the site
- Supabase stores accounts and saved mixes.
- Cloudflare hosts the website.
- Resend sends sign-in emails.
- Google AdSense shows ads to visitors without Premium.
- Paddle processes payments as Merchant of Record and handles receipts, taxes and refunds under its own privacy policy.
Some of these providers may process data outside Canada, such as in the United States.
Cookies and ads
We use cookies to keep you signed in and to remember your colour theme.
Free pages show a banner ad. When ads come from Google AdSense, Google and its partners may use cookies to show and measure ads, including ads based on your visits to this and other sites. You can turn off personalized ads at Google Ad Settings and learn more in how Google uses information from sites that use its services. Where the law requires it, we ask for your consent first. Premium members see no ads.
How long we keep it
We keep your account while it’s open. Delete it any time in Account; this removes this site’s data, including your saved mixes, right away. If you also use another ChowChow Labs site with the same email, your email stays on file for that site until you delete your account there too. Paddle keeps payment records as tax law requires.
Your rights
You can ask to see, correct or delete your personal information, or withdraw consent, by emailing chowchowbuy@gmail.com. If you’re not satisfied with our answer, you can contact the Office of the Privacy Commissioner of Canada.
Changes
If we change this policy, we’ll update the date above and email subscribers about important changes.
