Privacy Policy

Version 2026-07-29 · Effective 29 July 2026

This Privacy Policy explains how Flickwand LLC (“Flickwand,” “we,” “us”), a United States limited liability company that operates SonoRev, handles personal data when you use sonorev.com, the /app/ ride experience, and related services (the “Service”).

It should be read with our Terms of Service.

1. Who is responsible

Controller: Flickwand LLC (USA), operating SonoRev. Contact: [email protected].

If you are in the EU/EEA/UK, you may also have rights under the GDPR / UK GDPR as described below.

2. What we collect

Account: email address (magic-link sign-in via Supabase Auth); account identifiers.
Subscription: Stripe customer and subscription status, payment-related metadata Stripe shares with us (we do not store full card numbers).
Terms acceptance: Terms version, acceptance timestamp, and optionally user-agent (and similar technical signals) to show you agreed.
Preview anti-abuse: a browser install id and hashed network/IP signals, plus user-agent, so free preview time cannot be endlessly reset by clearing storage.
App preferences: settings stored in your browser (for example volume, profile, trip distance).
Device permissions you grant: location (GPS speed for the sound model), motion sensors, Bluetooth (optional battery %), wake lock / media playback APIs. Location and sensor streams are used in the browser to drive the ride experience; we do not build a trip history map on our servers.
Technical logs: standard hosting/CDN and infrastructure logs (IP, timestamps, error data) as needed to run and secure the Service.

3. Why we process data (purposes & legal bases)

Provide the Service (account, magic link, engine app, subscription entitlement) — contract / steps prior to contract (GDPR Art. 6(1)(b)).
Billing and fraud prevention (Stripe, preview ledger) — contract and legitimate interests in preventing abuse (Art. 6(1)(b), 6(1)(f)).
Record Terms acceptance — contract and legitimate interests in proving agreement (Art. 6(1)(b), 6(1)(f)).
Security, debugging, and service improvement — legitimate interests (Art. 6(1)(f)).
Legal obligations — where tax, accounting, or law-enforcement rules require retention (Art. 6(1)(c)).
Marketing — only if we start it, and then with a separate lawful basis (usually consent). We do not sell your personal data.

4. Processors and transfers

We use service providers that process data on our behalf, including:

Supabase — authentication, database, edge functions;
Stripe — payments and customer portal;
Hosting / CDN (for example DigitalOcean App Platform) — static site delivery.

These providers may process data in the United States or other countries. Where GDPR applies, transfers rely on appropriate safeguards such as the provider’s standard contractual clauses or other lawful transfer mechanisms they offer.

5. Retention

Account and subscription records: while your account is active and for a reasonable period afterward for billing disputes, abuse prevention, and legal retention.
Terms acceptance records: for the life of the account and a reasonable period after, to evidence agreement.
Preview ledger keys: while needed to enforce preview limits.
Browser-local settings: until you clear site data.

6. Your rights

Depending on where you live, you may have rights to access, correct, delete, restrict, or port your personal data, and to object to certain processing. EU/EEA/UK users may lodge a complaint with their local supervisory authority.

To exercise rights: [email protected]. We may need to verify you control the account email.

You can cancel a subscription in the Stripe Customer Portal. Deleting an account may require contacting us if self-serve deletion is not yet available in the app.

7. Children

The Service is not directed at children under 16 (or the higher digital-consent age where you live). We do not knowingly create accounts for younger children.

8. Safety note

SonoRev uses location and audio while you ride. That is a product feature, not a reason to interact with the phone in traffic. See the Terms for rider responsibility and assumption of risk.

9. Changes

We may update this Privacy Policy. The version and effective date above will change when we do. Material changes may be noted in the app or by email.
