Plumbline Privacy Policy

1. What stays on your iPhone

• Your journal: notes, applications, prayers, tags and study history are stored only on your device, in an encrypted database. We cannot see them.
• Settings and reminders: reading reminders and the weekly recap reminder are scheduled on your device. Notifications never show what you wrote.
• Prayers are never sent to us or to any AI service.

You can export your journal or delete all of your data at any time in Settings → Your data.

2. What leaves your iPhone, and why

Anonymous install ID. The app creates a random ID the first time it opens. It is not linked to your name, email, Apple ID or device identifiers. We use it to count the free daily study-guide allowance and to check whether you have Plumbline Pro.

AI study guide (only if you turn it on). The guide is off until you agree. When you ask for guidance, the app sends the passage you selected, the notes you choose to share in that step, and your follow-up questions, through our server to OpenAI, which writes the reply. Your prayers are never sent.

• We do not store the text you send or the replies. Our server keeps only the install ID, the date, how many replies were used, the number of AI tokens used (for cost tracking), and whether a reply was flagged for safety.
• OpenAI processes the request under its API terms. It does not use API data to train its models and may keep it for a limited time (up to 30 days) to detect abuse.
• If a message suggests someone may be in crisis, the app shows the 988 Suicide & Crisis Lifeline instead of an AI reply. Only the "flagged" status is logged, never the text.
• You can turn the guide off at any time in Settings.

Purchases. Payments are handled entirely by Apple; we never see your payment details. To confirm a subscription, the app uses RevenueCat, which receives the anonymous install ID and the App Store purchase record.

Ad attribution (Apple Ads). If you found Plumbline through an Apple Ads ad on the App Store, Apple's AdServices framework gives the app an anonymous attribution token, which is sent to RevenueCat. It tells us only which Apple Ads campaign and keyword led to the download, so we can see which ads work. It contains no name, email or device identifier, does not track you across other apps, and is never combined with your journal.

Ads (free version only). The free version shows ads from Google AdMob. We request non-personalized ads only: ads are not based on your reading, notes or prayers, and the app does not ask to track you across other apps. Google may still collect limited technical information (such as IP address and device type) to deliver ads, limit how often you see them, and prevent fraud. Plumbline Pro has no ads.

Bible text and audio. Scripture text and narration files are downloaded from our storage provider (Supabase). Like any web server, it may briefly record technical request data such as IP address.

"How did you hear about Plumbline?" If you answer this optional question, only your answer and the date are saved, with no ID attached.

3. What we don't do

• We don't sell or "share" personal information (as those terms are defined under California law).
• We don't use your journal for advertising, analytics or AI training.
• We don't ask for your name, email, location, contacts or photos.

4. Service providers

Supabase (servers and storage), OpenAI (AI study guide), RevenueCat (subscription status), Google AdMob (ads in the free version), Apple (App Store payments and notifications). They may process data in the United States and other countries, only to provide their service to us.

5. Retention

Journal data stays on your device until you delete it or delete the app. The limited server records described above contain no names or journal text and are kept only as long as needed to run the daily allowance, keep costs under control and keep the service safe.

6. Children

Plumbline is not directed at children under 13, and we do not knowingly collect personal information from them.

7. Your choices and rights

• Turn the AI guide off, stop reminders, or delete all data in the app.
• Cancel a subscription in your iPhone's Settings → [your name] → Subscriptions.
• Depending on where you live (for example California), you may have the right to ask what information we hold about you and to ask us to delete it. Because we don't know who you are, please include the date and time you used the guide so we can find the related records. Write to dev@sarperdijital.com.

8. Changes

If we change this policy, we'll update the date above and, for important changes, tell you in the app.
