Privacy policy
This page was last updated on August 19, 2026.
1. Introduction
Sulu GPS ("we," "our," "us") provides GPS-triggered audio tours through our mobile app for iOS and Android. This policy explains what information we collect when you use the app or our website, how we use it, who we share it with, and how long we keep it. Sulu GPS is located at 224 7th St, San Francisco, CA 94103.
2. Information we collect
Contact details for tour access. Tours are unlocked with a single-use code. When you book a tour through one of our tour-operator partners, the operator's booking system sends us the email address or mobile number from your booking (and, with some bookings, your name) so we can deliver your code. If you request a code directly from us, we collect the email address or mobile number you provide. If you choose text-message delivery, we ask for your consent to send the code by SMS.
Location, on your device. While the app is open during a tour, it uses your device's precise location to show your position on the map and to play the right audio at the right place. This processing happens on your device. We do not transmit your GPS coordinates to our servers, and we do not track your location when the app is not in use. The app does not request background location access.
Tour activity. We record which tour you take, which stops you reach and when, and audio playback events. Because your unlock code is issued to your email address or phone number, tour activity may be associated with your booking contact details. We use tour history to improve our tours and personalize your experience, including recommending tours that may interest you.
Device and diagnostic data. To keep the app working we collect technical information: device model, operating system version, app version, language, memory, and connection status, along with app logs and crash reports. If the app encounters an error, our error-reporting service may capture a screen recording of the session to help us diagnose it. Text and images in these recordings are masked; recordings may include app screens such as the tour map.
What we don't collect. The app has no user accounts and no advertising or analytics trackers. We do not collect contacts, photos, or microphone audio, and we do not use your data for advertising.
3. How we use your information
- To deliver your unlock code and provide the tour you booked.
- To play location-triggered audio and show your position during a tour.
- To understand how tours are used, improve them, and recommend tours that may interest you.
- To operate, debug, and improve the app using diagnostic data.
- To meet legal obligations and resolve disputes about bookings.
4. Who we share it with
We do not sell your personal information, and we do not share it with advertisers. We share data only with service providers that operate the app on our behalf:
- Booking platforms used by your tour operator, which send us your booking contact details and receive tour status updates.
- Message delivery providers that send your unlock code by SMS (Twilio) or email (Mailgun).
- Maps (Mapbox), which receives standard map-tile requests from your device, including your IP address.
- Diagnostics and crash reporting (Datadog, Sentry), which receive the device and diagnostic data described above.
- Hosting and content delivery providers that run our servers and deliver tour audio.
We may also disclose information if required by law, or as part of a merger, acquisition, or sale of assets — in which case this policy continues to apply to your data.
5. Tour operators
Your booking itself — payment, party details, and any information you gave when booking — is held by the tour operator you booked with, under that operator's own privacy policy. We receive from the operator only what we need to deliver your tour.
6. How long we keep it
- Booking and unlock-code records (your contact details and code) are kept for as long as needed to operate the service and to resolve billing or booking disputes with your tour operator.
- Tour activity records are retained for service analytics, reliability, and personalization for as long as we offer the service.
- Logs and crash reports are retained by our diagnostics providers for limited periods — typically no more than 90 days — after which they expire automatically.
- On your device, downloaded tour content and settings remain until you delete them or uninstall the app.
You can ask us to delete your personal data at any time — see the next section — and we will honor the request except where we must keep a record to comply with law or resolve an active dispute.
7. Your rights and choices
You may request access to, correction of, or deletion of your personal data by emailing support@sulugps.com. We respond within 30 days. Depending on where you live (including the EEA/UK under GDPR and California under CCPA/CPRA), you may have additional rights, such as portability and the right to complain to a supervisory authority; we honor these regardless of which law applies. We do not sell or share personal information for cross-context behavioral advertising, so there is no need for an opt-out. You can disable location access in your device settings at any time; tours will not be able to trigger audio automatically without it.
8. Children
The app is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us personal information, contact us and we will delete it.
9. International transfers
We are based in the United States and process data on servers located there. If you use the app from outside the U.S., your information will be transferred to and processed in the U.S.
10. Security
We protect your information with measures appropriate to its sensitivity, including encryption in transit and restricted access to production systems. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
11. Changes to this policy
When we make material changes we will update the date at the top of this page and, where appropriate, notify you in the app. Continued use of the app after a change means the updated policy applies.
