Daily Chain is a habit tracker. This page explains what the app keeps about you, why it keeps it, and how you can remove it.
| Information | How we get it | What it is used for |
|---|---|---|
| Name | You type it in when you set up the app. | Greeting you and labeling your account. |
| Email address | Comes from your Google account when you sign in. | Identifying your account and contacting you about it. |
| Google sign-in | Google confirms who you are when you choose Sign in with Google. | Letting you sign in and sync across devices. We never see your Google password. |
| Your habits | You create habits or install a Protocol Pack, then tap to mark them done. | Showing streaks, charts and your calendar grid. This includes habit names, reminder times, completion dates and supplement check-offs. |
| App settings | You choose them in Settings. | Remembering your theme and reminder times. |
| Usage and device information | Collected automatically by Google Analytics for Firebase while you use the app. | Understanding which features are used and fixing problems. This includes screens viewed, taps on features, app version, browser or device type, language, approximate region from your IP address, and an anonymous app identifier. |
| Daily usage counts | Added up by the app from your activity. | Anonymous totals, such as how many habits were completed in a day, so we can see how the app is being used overall. |
| Anonymous ID | Created automatically the first time you open the app. | Saving your habits before you sign in. It becomes your account if you later sign in with Google. |
Apart from what is listed here, we do not collect other personal information about you.
We use Google Analytics for Firebase to measure how Daily Chain is used. It collects the usage and device information listed above and uses an anonymous app identifier to tell one installation from another. We do not give Google your name or email address for analytics, and we do not use analytics to build advertising profiles or to show ads.
Google processes this data for us and under its own terms. You can read how Google handles it in the Google Privacy Policy. We only turn it on if you allow it, and you can change your choice any time in Settings. A browser setting or extension that blocks analytics will also stop this collection.
Many habits relate to sleep, exercise, food or supplements. These are entries you choose to make, and Daily Chain stores them only so you can track them. We do not collect medical records, diagnoses, lab results, prescriptions or insurance information.
Protocol Packs summarize published research and expert recommendations. They are educational and are not medical advice. Talk with a doctor or pharmacist before starting a supplement or changing a routine, especially if you are pregnant, have a health condition, or take medication.
Purchases of packs and Pro plans are handled by Stripe. When you pay, you give your payment details, such as your card number, billing details and email address, to Stripe, and they never reach our servers. Stripe tells us what you bought and whether your plan is active, and that is all we keep about the payment. Stripe uses your information under its own terms, described in the Stripe Privacy Policy.
We use these outside services to run Daily Chain:
We share information with these providers only so they can run the app, measure its use and take payments. We do not sell or rent your information to anyone. We would share it only if the law requires us to.
Daily Chain stores your sign-in and some settings in your browser or phone. Clearing your browser's site data removes them, and if you haven't signed in with Google or email, you may lose access to your habits. Data saved to your account stays there until you remove it. Daily Chain needs an internet connection to save your check-offs.
We keep your information while your account is open. A record of your plan status is kept for billing and refunds. Stripe keeps its own payment records for as long as the law requires.
Daily Chain is not made for children under 13, and we do not knowingly collect information from them. If you believe a child has given us information, email us and we will delete it.
If we change what we collect or how we use it, we will update this page and the date at the top. For significant changes we will also tell you in the app.
