Privacy Policy
Last updated: 7 June 2026
This Privacy Policy explains how the Ember team (“Ember”, “we”, “us”) handles information in connection with the Ember mobile app (the “App”) and the website at saunadiscovery.com (together, the “Service”).
The short version: Ember does not require an account and does not collect personal information about you. Your check-ins, saved places, passport, and home region stay on your device. We can't see them, and they are never uploaded to our servers.
No account, no sign-in
Ember has no user accounts, logins, or sign-ups. We do not ask for your name, email address, phone number, or any other identifier to use the Service.
Information stored on your device
As you use the App, it stores the following on your device only:
- Your check-ins (the venue and the date you checked in) and the stamps and streaks that build your passport
- The saunas you save
- Your chosen home region and whether you've completed onboarding
This information never leaves your device, and we have no access to it. If you delete the App, this data is removed with it.
Location
If you choose to grant location access, the App uses your location only on your device to confirm you're near a sauna when you check in, and to determine which country you're in for your passport. Your location is used in the moment and is never stored on, or transmitted to, our servers or any third party. Location access is optional and you can change it any time in your device settings.
The sauna catalog
To show you saunas, the App and website fetch our curated catalog from our hosting provider, Supabase. These are read-only requests for public sauna content; no personal information is sent. As with any internet request, the provider may process technical data such as your device's IP address to deliver the response.
Purchases
Ember Pro subscriptions and region unlocks are sold through the Apple App Store. Apple processes your payment and manages your subscription — we never see or store your payment details. Apple shares only the entitlement (whether a purchase is active), which the App reads on your device.
Website analytics
On saunadiscovery.com we use Vercel Web Analytics to understand aggregate traffic, such as which pages are popular. It measures visits without cookies and without building a profile of you, and does not collect personal information. The App itself contains no analytics, tracking, or advertising SDKs.
Cookies
The website does not use tracking or advertising cookies. The App does not use cookies at all.
Maps and outbound links
Maps are rendered using Apple Maps in the App, and CARTO with OpenStreetMap data on the website; loading map tiles sends standard technical request data (such as an IP address) to those providers. When you tap a venue's website or booking link, you leave Ember and that destination's own privacy practices apply.
Third-party providers
The providers that may process technical data on our behalf or as part of delivering the Service are: Apple (App Store, purchases, and Apple Maps), Supabase (catalog hosting), Vercel (website hosting and analytics), and CARTO/OpenStreetMap (website map tiles). We do not sell your data, and we do not share personal information with advertisers.
Children
Ember is not directed at children and does not knowingly collect information from children.
Your rights
Because we don't hold personal information about you on our servers, there is no account data for us to access, correct, or delete. You are in control of the data stored on your device: you can remove it at any time by deleting the App. If you have questions about your rights under laws such as the UK GDPR or GDPR, contact us using the details below.
Changes to this policy
We may update this policy from time to time. When we do, we will revise the “Last updated” date above.
