Walt is published by Embedded Engineering ApS, a company registered in Denmark. This policy covers two things: how the walt.is website handles data when you join the waitlist, and how the Walt Android app handles data on your device.

Website & waitlist
Controller
Embedded Engineering ApS, Godsbanegade 31, 1722 Copenhagen, Denmark (CVR 45749355) is the data controller for personal data collected through walt.is. Privacy contact: privacy@walt.is.
What is collected and why
When you join the waitlist, Walt collects the email address you submit. It is used to manage the waitlist and to send product updates about Walt. No other personal data is collected through the form.
Lawful basis
Processing is based on your consent under GDPR Article 6(1)(a). You give consent by submitting the waitlist form after reading the inline notice on the form. You can withdraw consent at any time using the unsubscribe link in every email, or by emailing privacy@walt.is. Withdrawal does not affect processing that already took place under your earlier consent.
Who processes your data
Walt uses the following processors to operate the website and send waitlist emails:
- Resend — delivers waitlist confirmation and product update emails. Resend is a US company; the data protection addendum is available at resend.com/legal/dpa.
- Vercel — hosts the walt.is website and serverless functions that handle waitlist submissions. Vercel is a US company. Their DPA is available at vercel.com/legal/dpa.
- Plausible — provides cookieless, EU-hosted website analytics. No cookies are set, no cross-site identifiers are used, and visitor IPs are not stored.
International transfers
Resend and Vercel are based in the United States, so your email address and waitlist submission metadata are transferred to the US for processing. Transfers rely on the EU Standard Contractual Clauses incorporated in each provider's data protection addendum. Walt is actively working to move waitlist email delivery and website hosting to EU-based providers; this section will be updated when that migration is complete.
Retention
Your email is kept on the waitlist until you unsubscribe. After unsubscribe, the address is retained for a short grace period (up to 30 days) to honor the unsubscribe and prevent accidental re-subscription, and is then deleted from active systems. Provider backups roll off on each provider's own schedule.
Cookies and tracking
walt.is sets no cookies and uses no cross-site trackers. Plausible analytics is cookieless.
Your rights
Under GDPR you have the right to:
- access the personal data Walt holds about you,
- have inaccurate data corrected,
- have your data deleted,
- receive your data in a portable, machine-readable form,
- object to processing,
- withdraw consent at any time without affecting prior lawful processing.
To exercise any of these rights, email privacy@walt.is. You also have the right to lodge a complaint with the Danish supervisory authority, Datatilsynet, Carl Jacobsens Vej 35, 2500 Valby, Denmark.
Android app
The following sections describe how the Walt Android app handles your data.
What the current release does
The current release of Walt is a passes wallet. You can import digital passes (boarding passes, event tickets, loyalty cards, and similar .pkpass files) into the app, view their details, and display their barcodes. Passes are imported through Android's share sheet or by opening a .pkpass file from another app.
All passes you import are stored in Walt's private app-sandbox storage on your device. Walt does not transmit pass data, pass barcodes, or pass contents off your device. There is no Walt account, no server-side database of your passes, and no telemetry that records what passes you hold or how you use them.
Push notifications
Walt uses Firebase Cloud Messaging (FCM) to deliver push notifications. When the app starts, Google issues a device-specific FCM registration token to the Walt app. This token is required for Google to route push messages to your device and is handled by Google as part of FCM. Walt does not associate this token with any identity, name, email, or pass content.
Payments
Tap-to-pay and bank-card features are a planned future capability and are not active in the current release. Any payment functionality is pending regulatory and compliance review and is disabled in the shipping app. When and if these features are introduced, this policy will be updated to describe how card and transaction data are handled before the functionality is enabled for users.
Data deletion
Walt stores all pass data locally on your device. There is no server-side account to delete and no central database holding your passes.
To delete your Walt data:
- Open Android Settings on your phone.
- Tap Apps and find Walt in the list.
- Tap Storage and cache, then Clear storage. This deletes all imported passes, pass barcodes, pass details, and app preferences immediately.
Or, to remove Walt entirely:
- Long-press the Walt app icon and tap Uninstall.
- Confirm. Android removes the app and all of its data.
What gets deleted: every pass you imported, all pass barcodes and details, app preferences, and the device's Firebase Cloud Messaging registration token.
What Walt retains after deletion: nothing. Walt does not transmit pass data off your device, so there is no copy on any server to retain.
