Privacy Policy
Last updated 12 September 2026
The Argo mobile application, website, and related services (collectively, the “Service”) are provided by Brian Tseng, an individual doing business as Argo Labs (“Argo,” “we,” “us,” or “our”). Argo helps you record, organize, and revisit hotel stays.
This Privacy Policy explains what information we collect, how we use and share it, and the choices available to you.
Information we collect
Account information
When you create or use an Argo account, we collect:
- Your Firebase account identifier.
- Your email address, when supplied by your sign-in provider.
- Your display name, if provided by you or your sign-in provider.
- Your sign-in method, such as Sign in with Apple or Google Sign-In.
- If you use Sign in with Apple and elect to hide your email address, we may receive Apple’s private email relay address instead of your personal email address.
We do not receive or store your Apple ID password, Google password, or payment-card information.
Your hotel collection and travel information
When you use Argo, we collect the information you add or generate in the Service, including:
- Hotel names, addresses, cities, countries, coordinates, place identifiers, websites, phone numbers, photos, and hotel-group information.
- Stay dates, ratings, favorites, rankings, notes, room numbers, and optional spending information.
- Profile preferences and app settings, including your hotel priorities, member-card preferences, and notification preferences.
- Calendar event identifiers for calendar events created by Argo.
- Information used to generate your maps, statistics, travel insights, achievements, and hotel collection.
This information may reveal details about your travel history and future travel plans.
Photos
If you choose photos from your photo library for a hotel gallery, Argo processes and stores a local copy on your device to display it in the app. For cross-device gallery restoration, Argo may store a Photos cloud identifier and the gallery order in our cloud database. Argo does not upload the original image file from your photo library to our servers.
You control photo-library access through your device settings. If you revoke access, some gallery photos may no longer be available in Argo.
Calendar and notifications
Calendar access is optional. If you enable it, Argo creates a dedicated “Argo” calendar and adds upcoming stays to it. Argo reads and updates only events it created, so it can keep those events current or remove them when you turn calendar sync off.
Argo may schedule local notifications on your device for upcoming stays and rating reminders after you grant notification permission. Argo does not use remote push notifications for advertising or marketing.
Analytics and technical information
We use Firebase Analytics to understand how people use Argo and to improve the Service. This may include:
- App interactions and feature usage.
- Subscription-plan and purchase-funnel events.
- Counts describing your collection, such as the number of hotels, countries, stays, or photos it contains.
- Notification status, app version, operating-system version, device and app-instance identifiers, and diagnostic information.
These analytics events do not include hotel names, addresses, notes, ratings, or spending information. We do not use analytics data for targeted advertising, do not sell personal information, and do not use the IDFA for advertising tracking.
Booking searches and external links
If you use “Book Again” or check hotel rates, Argo sends the hotel’s name, its city and country, its coordinates where we hold them, and the check-in and check-out dates you selected to Stay22 in order to obtain accommodation options.
These requests are made by Argo’s servers rather than from your device. Stay22 receives the search details described above, and does not receive your device’s network address, your name, or your email address.
Rate results are shown to you for that search only. Argo does not store the options Stay22 returns, and they do not alter anything in your hotel collection.
When you open a booking link, you leave Argo and interact directly with the relevant booking provider. That provider’s privacy policy governs information it collects from you on its website or app.
Argo may receive compensation from booking partners when you use certain booking links.
Shared stay links
If you create a Shared Stay link, Argo creates a link that contains a limited snapshot of the stay: hotel information, location, dates, and a hotel photo reference where available. It does not include your name, email address, ratings, notes, spending information, room number, or account identifier.
Anyone with the link may access that shared snapshot until it expires, normally after 30 days. Shared snapshots are not linked to your account and cannot be withdrawn individually once created, so treat a share link as public to anyone you give it to.
Website waitlist and support communications
If you join our website waitlist, we collect your email address to manage the waitlist and send launch-related communications.
If you contact us, we collect the information you include in your message, such as your email address, device details, and support request.
How we use information
We use information to:
- Create and secure your account.
- Provide, personalize, maintain, and sync your hotel collection across your devices.
- Generate maps, statistics, rankings, insights, and achievements.
- Provide optional photo, calendar, notification, sharing, and booking features.
- Process and verify Argo Club subscriptions and prevent subscription fraud.
- Respond to support requests.
- Monitor reliability, troubleshoot problems, protect the Service, and improve its features.
- Comply with legal obligations and enforce our terms.
We process information as necessary to provide the Service, protect the Service and its users, comply with legal obligations, or pursue legitimate business interests that do not override your rights.
How we share information
We share information only as described below:
- Google Firebase: We use Firebase Authentication, Firestore, Cloud Functions, Hosting, and Analytics to operate Argo, authenticate users, store and sync account data, process service functions, and understand app usage.
- Google Sign-In and Google Places: We use Google Sign-In for optional authentication and Google Places to search for hotels, obtain hotel details, and display hotel photos and attribution.
- Apple: Apple processes Sign in with Apple, App Store subscriptions, calendar access, photo-library access, maps, and device notifications according to Apple’s terms and privacy practices.
- Stay22: When you request rates, our servers send Stay22 the hotel and date details for that search.
- Booking providers: When you open a booking option, you leave Argo and deal with that provider directly.
- Service providers: We may use vendors that process information on our behalf to host, secure, maintain, or support the Service.
- Legal, safety, and business transfers: We may disclose information when required by law, to protect rights and safety, prevent fraud, or in connection with a merger, acquisition, financing, or sale of assets.
We require service providers to handle personal information in a manner consistent with this Privacy Policy and applicable law.
We do not sell personal information or share it for cross-context behavioral advertising.
Data retention
We retain account and collection data while your account is active and for as long as needed to provide the Service.
When you delete your account, we delete or de-identify your account information, hotel collection, gallery metadata, local app data, and other associated personal data, except where retention is required or permitted by law, such as for security, fraud prevention, tax, accounting, or subscription-recordkeeping obligations.
Deleting your account also deletes our server-side record of your Argo Club subscription, along with the internal references that connect your Argo account to the corresponding Apple transaction. We do not keep those references after deletion.
Billing is separate from that record. An Argo Club subscription is billed by Apple and continues until you cancel it through your Apple Account subscription settings, whether or not your Argo account still exists. If you later create a new Argo account and use Restore Purchases on the same Apple Account, Restore Purchases restores Argo Club access only. It does not, and cannot, restore the hotel collection, photos, profile, or other Argo data that was deleted with your previous account.
Shared Stay links are the exception. Because a shared snapshot is deliberately stored without any link to the account that created it, we cannot locate or remove an individual link on request. Shared snapshots expire on their own, normally 30 days after creation, and deleting your account does not delete them sooner.
Backups may retain limited information for a short period before they are overwritten under normal backup processes.
Your choices and rights
You can:
- Update your display name and preferences in the app.
- Control photo-library, calendar, and notification permissions in your device settings.
- Disable calendar sync in Argo; this removes Argo’s dedicated calendar and its events.
- Delete your Argo account from the app’s Settings screen.
- Cancel an Argo Club subscription through your Apple Account subscription settings. Deleting your Argo account does not automatically cancel a subscription billed by Apple.
- Request access, correction, export, or deletion of your personal information by contacting us.
Depending on where you live, you may have additional privacy rights. To exercise them, contact us at support.argo@gmail.com.
International data transfers
Argo and our service providers may process information in the United States and other countries where they operate. Where required, we use appropriate safeguards for international transfers of personal information.
Children
Argo is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, contact us so we can take appropriate action.
Security
We use reasonable administrative, technical, and organizational measures designed to protect information. No method of transmission or storage is completely secure, however, and we cannot guarantee absolute security.
Changes to this policy
We may update this Privacy Policy from time to time. If we make material changes, we will update the “Last updated” date and provide additional notice where required by law.
