Privacy Policy

1. Overview

This policy describes how Whittr (“Whittr,” “we,” or “us”) collects, uses, and shares information when you visit whittr.app, join the waitlist, shop through Whittr links, or use the Whittr iOS app.

Whittr is a cosmetic routine companion. Shade estimates, progress views, plans, and AI Coach replies are not medical diagnoses or dental treatment. They do not replace care from a licensed dentist.

2. Information we collect

Depending on how you use Whittr, we may collect:

• Account details such as email address, display name, and optional profile photo.
• Onboarding and routine data such as shade goals, sensitivity notes, quiz answers, plans, task completions, and progress entries.
• Scan images and analysis such as smile or teeth photos you capture or upload, together with derived shade scores and color measurements.
• Coach messages you send to AI Coach, plus the replies generated for you.
• Subscription status associated with App Store purchases, such as plan tier. Apple processes payment details; we do not receive your full card number.
• Waitlist details if you join from the website: your email address, a product source tag, and a hashed network address used only to limit abuse.
• Device permissions you grant, including Camera, Photo Library, and Notifications. We do not access those systems until you allow them.
• Technical data needed to operate the service, such as authentication tokens, timestamps, and basic request logs.

3. How we use information

We use this information to create and secure your account, generate and update whitening routines, show personal progress, send reminders you enable, provide AI Coach replies, process waitlist requests, verify subscriptions, prevent abuse, and improve the product.

We do not sell personal information. We do not use scan photos for advertising. We do not train public generative models on your smile photos.

4. Photos and shade analysis

Scan photos stay in your account so you can review progress over time. They are stored privately and are visible only to you, except as needed for us to operate, secure, or debug the service, or if the law requires disclosure.

On-device analysis may estimate shade, brightness, and related cosmetic scores from the photo you provide. Lighting, hydration, camera quality, and capture angle can change those estimates. Treat them as a personal tracking aid, not a clinical measurement.

5. AI Coach

If you use AI Coach, your prompt and limited routine context are sent to our servers and then to a contracted language-model provider so we can generate a reply. Do not include information you do not want processed for that purpose. Coach answers are general whitening tips, not medical, dental, or professional advice.

6. Sharing

We share information with service providers who help us run Whittr, including hosting, authentication, file storage, purchase verification, and AI inference. Those providers may process data only on our instructions, except where they act as independent controllers (for example, Apple for App Store billing).

If you follow a recommended product link, the destination shop may collect its own information under that shop’s policy. Whittr may earn a commission from those purchases.

We may disclose information if required by law, to protect Whittr or other people from harm, or as part of a merger, acquisition, or similar transaction, with appropriate safeguards.

7. Retention and security

We keep account, scan, and routine data while your account is active. Waitlist emails are kept until you ask to be removed or we close the list. If you delete your account in the app, we delete associated account records and take reasonable steps to remove stored scan images.

We use encrypted transport, access controls, and private storage buckets. No method of storage or transmission is completely secure, so we cannot guarantee absolute security.

8. Your choices and rights

You can update profile details in the app, turn notifications off in iOS Settings, and withdraw camera or photo access at any time. You can delete your Whittr account from Profile in the app.

Depending on where you live, you may also have the right to access, correct, delete, or export personal information, or to object to certain processing. To make a request, email hello@whittr.app. We may need to verify your identity first.

If you joined the website waitlist, email the same address to unsubscribe. We do not use waitlist addresses for unrelated marketing lists.

9. Children

Whittr 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 created an account, contact us and we will delete it.

10. International processing

We may process information in Canada, the United States, or other countries where our providers operate. Those locations may have privacy laws that differ from the laws where you live.

11. Changes

We may update this policy as Whittr changes. The “Last updated” date will change when we do. Continued use of Whittr after an update means you accept the revised policy.

12. Contact
