Privacy policy

The short version

Your health data stays on your device and in your own private iCloud. We do not collect it, we cannot read it, and we never sell or share it. The app has no accounts and no server of ours holding your information.

What the app stores, and where

• Your treatment log (medication, doses, side effects, weight, notes) is stored on your iPhone and synced through your personal iCloud account using Apple's CloudKit, in your private database. Only you can access it. Deleting the app and its iCloud data removes it.
• Apple Health: with your permission, the app reads and writes your weight, and on supported iOS versions reads medication logs you keep in the Health app. Health data is used only to show your own information inside the app. It is never used for advertising, marketing, or data mining, and it is never shared with third parties.
• A random identifier (a UUID that contains no personal information) is stored in your device Keychain and attached to App Store purchases so we can verify subscriptions. It is not linked to your identity.

What we do not do

• No accounts, no sign up, no email collection.
• No third-party analytics or advertising SDKs ship in the app today.
• No health information ever leaves your device or your iCloud, and none of it is included in any analytics.

Tracking

The app may ask for permission to track using Apple's App Tracking Transparency prompt. If you decline, nothing changes in how the app works. No tracking takes place without your explicit permission.

Payments

Subscriptions are processed by Apple through your App Store account. We never see your payment details.

Your choices

You can revoke Health access in Settings, delete any entry inside the app, disable iCloud sync for the app in iOS Settings, or delete the app entirely. Questions or requests: support@digitalnafta.com.

Changes

If this policy changes, the updated version will be posted at this address with a new effective date.

This website

The app and the website are separate, and this section is about the website you are reading now.

• The curve calculator does not send us anything. Everything you enter is used by JavaScript in your own browser to draw the chart. Nothing is posted to a server, nothing is written into the URL, and nothing is stored after you close the tab.
• The email boxes are the only thing that reaches us. If you join the waitlist or ask us to send you your curve, we store the address you typed, the page you were on, the date, and whichever options you ticked. Nothing else. We use it to email you what you asked for.
• We never sell, rent or share your email address. There are no advertising pixels, no third-party analytics scripts and no cookies set by this site.
• Deleting your data. Write to jannafta@gmail.com and ask. We remove the address and confirm it. You do not need to explain why.
• Where it lives. Email addresses are stored on our web host in a file that is not reachable from the web, and a copy of each signup is emailed to the team.
• Our web host keeps standard server access logs, which include IP addresses, as every web server does. We do not use them to build any profile of you.
