Privacy Policy

henlo! ("we," "us," or "our") is a pet safety product made by a solo founder based in the United States. We make smart pet ID tags that use QR codes and NFC to help reunite lost pets with their owners. You can reach us at adam@henlotag.com.

Information you give us

• Account information: your email address, name, and phone number when you create an account.
• Pet profile: your pet's name, species, breed, gender, date of birth, color, microchip number, medical notes, and profile photo.
• Emergency contacts: names, phone numbers, and relationships of people you add to your pet's profile.
• Waitlist: your email address and tag preferences if you sign up for launch notifications on our website.

Information collected automatically when your tag is scanned

• IP address of the device that scanned the tag.
• Approximate city derived from the IP address (not GPS-level precision).
• GPS coordinates only if the scanner's browser shares location and you have lost mode enabled.
• Device user agent (browser/OS type).
• Scan timestamp.

Information from third-party services

• Authentication: We use Clerk (clerk.com) to handle sign-in. Clerk may collect device identifiers and session data per their own privacy policy.
• Push notifications: If you enable scan alerts, we store your device's push notification token to send you notifications.

• Display your contact information to anyone who scans your pet's tag.
• Send you push notifications when your tag is scanned (if enabled).
• Show you a scan history so you can track when and where your tag was scanned.
• Contact you about your account or order.
• Notify waitlist members when henlo! tags become available for purchase.
• Improve the product based on aggregate, anonymized usage patterns.

We do not sell your personal information. We do not use your data for advertising.

When someone scans your tag, they can see the information you have chosen to add to your pet's public profile: pet name, photo, species, breed, your first name, and your phone number. Emergency contact information is also shown to scanners. You control what you add. You can remove or update any information at any time from the app.

Scan events (IP address, city, timestamp) are visible only to you in your account dashboard. They are never shown publicly.

We share your data only in these limited circumstances:

• Service providers: We use Railway (database hosting), Cloudflare R2 (photo storage), Clerk (authentication), and Vercel (website hosting). These providers process data on our behalf and are contractually bound to protect it.
• Legal requirements: If required by law, court order, or to protect the safety of a person.
• Business transfer: If henlo! is acquired or merges with another company, your data may transfer as part of that transaction. We will notify you via email.

We retain your account data for as long as your account is active. If you delete your account, we delete your personal information within 30 days, except where we are required to retain it by law.

Scan records are retained for 2 years and then automatically deleted.

• Access and correction: You can view and edit your account and pet information at any time in the app.
• Delete your account: Email us at adam@henlotag.com and we will delete your account and all associated data within 30 days.
• Opt out of notifications: You can disable push notifications in your phone's settings at any time.
• Lost mode location: GPS location sharing during a scan only occurs if the scanner's browser prompts and they accept. You cannot control this, but location data is only used to help you find your pet.

If you are in the European Economic Area or California, you may have additional rights under GDPR or CCPA. Please contact us at adam@henlotag.com to exercise them.

henlo! is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe we have done so, please contact us and we will delete the information promptly.

We use industry-standard security practices including encrypted connections (HTTPS/TLS), secure database hosting, and third-party authentication. No system is perfectly secure — if you believe your account has been compromised, contact us immediately.

We may update this policy from time to time. We will notify you of material changes by email or by posting a notice in the app. The effective date at the top of this page will always reflect the most recent version.
