Dahlia

Privacy Policy

Last updated: October 2, 2026

This policy explains what Dahlia — the website at dahliawell.com and the Dahlia app — collects, how it is used, and the choices you have. The short version, and our promise: we never sell your personal information, and we never share your health answers for advertising.

What we collect

What we never collect: your card details. Your card number and security code go straight from the payment form to Stripe (or, if you pay with PayPal, stay with PayPal). They never reach our servers or our database.

How we use it

What we never do

Who we share information with

We use a small number of service providers who process information on our behalf and under our instructions:

We may also disclose information where the law requires it, or to protect the rights, safety, or property of Dahlia or others.

In the Dahlia app

Meal photos, voice clips and your Ask Dahlia messages are processed by OpenAI to estimate your meal or answer you. They’re never used to train AI; OpenAI may keep them up to 30 days to guard against abuse, then deletes them. Dahlia deletes voice clips as soon as they’re transcribed; meal photos stay in your account until you delete the entry or your account; chats stay in your account until you delete your account. Deleted photos and voice clips stay in our cloud provider’s recovery store for 7 days, then are erased for good. A barcode missing from our index is looked up on Open Food Facts from your phone — they see the barcode, never your account details.

Before you first use photo or voice logging or Ask Dahlia, the app asks your permission to send them to OpenAI, along with the logs Dahlia needs to answer you. You can turn these features off at any time in Settings → Privacy → AI features.

Subscriptions bought inside the app are processed by Apple (App Store) or Google (Google Play), and managed for us by RevenueCat.

Apple Health and Health Connect

If you allow it, the Dahlia app connects to Apple Health (on iPhone) or Health Connect (on Android).

Readings Dahlia imports are kept in your account, with the rest of your logs. They’re never used for advertising or marketing, and never sold. They’re shared with OpenAI only when you use Ask Dahlia, with your permission. You can change what Dahlia may read and write at any time in Apple Health or Health Connect.

Cookies and local storage

Dahlia sets a visitor cookie (kept for about a year) and a session cookie, keeps your in-progress answers in your browser’s local storage, and uses the measurement tools above, which set their own cookies. Our payment providers set their own cookies on the payment form to keep payments secure. You can clear or block these in your browser settings — parts of the Service, like resuming a plan in progress or paying, may stop working without them.

How long we keep information

We keep the information described above for as long as it is needed for the purposes in this policy — including keeping records of purchases for as long as the law requires — and delete it when it no longer is, or when you ask us to.

Deleting your account

You can delete your Dahlia account in the app (Settings → Privacy → Delete account) or by email — see Delete your Dahlia account. Deleting removes your account, logs, meal photos and voice clips, chats and settings. Deleted photos and voice clips stay in our cloud provider’s recovery store for 7 days, then are erased for good. Deleting your account doesn’t cancel a subscription — here’s how to cancel.

Your choices

Security

We use reasonable technical and organizational safeguards to protect your information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Children

The Service is for adults. It is not directed at anyone under 18, and we do not knowingly collect information from them.

Changes to this policy

If we make material changes, we will update the date at the top of this page. Your continued use of the Service after a change means you accept the updated policy.
