Privacy policy

Last updated November 3, 2026.

We collect as little as we can. We don't sell your information, and we don't run tracking ads.

If you're just browsing

• You don't need an account, a name, or an email.
• Your browser gets a random guest ID so your hearts count once. It isn't tied to who you are.
• We don't ask for your location. Routes start from landmarks you pick.

If you list your home

• We keep your email address to sign you in. It is never shown on the map.
• Your display name, address, pin, nights, description, and photo are public on the map. That's the point of listing.
• We never show owner names.

If you ask for the map in your town

• We keep your email, the town you name, and anything else you add (name, organization), only to talk with you about bringing the map there. We delete it when you ask.

If you buy a sponsored pin

• We keep your email, phone number, business name, and the ad you submit. Your email and phone are never shown on the map.
• Stripe handles payment. We never see or store your card number.

Kids

Families can browse without giving any personal information. Accounts for listing a home or a business are for adults 18 and older. We don't knowingly collect personal information from children under 13. If you think a child has given us information, email us and we'll delete it.

Who helps us run the site

• Google Firebase stores listings, photos, and sign-ins, and sends sign-in emails.
• Mapbox draws the map and suggests addresses. It sees map requests and your IP address.
• Vercel hosts the site and keeps short-term server logs.
• Stripe processes payments for sponsored pins.
• Resend sends emails about sponsored pin orders.

Each follows its own privacy policy. We share only what each needs to do its job.

On your device

We store your sign-in and a few settings in your browser so the site works. We don't use advertising cookies or cross-site tracking.

Keeping and deleting

• When you remove a listing, it and its photo are deleted.
• We clear old listings after each season unless you ask us to keep yours.
• To see, fix, or delete anything we have about you, email admin@bwstack.dev. We reply within 30 days.
