Privacy Policy
Last updated 18 October 2026
Eunice is a Christian faith companion app for iPhone. You talk to her, you journal, you pray; she remembers what you tell her so she can be useful tomorrow. That only works if you trust us with what you say, so here is exactly what we do with it.
Who we are
Eunice is made by Dalyn Butler, an independent developer. You can reach us at dalynbutler@gmail.com. We are the "data controller" for the information described here.
What we collect
- Your first name, so Eunice can address you. You can use a nickname or leave it blank.
- Your settings: the time you want your morning verse, your time zone, quiet hours, your preferred Bible translation, and the growth areas you chose (for example patience, prayer, anxiety).
- Your conversations: every message you send to Eunice and every reply she gives, stored on our server. This is how she replies in context and remembers things like "interview Thursday" or your kids' names.
- Your journal entries: the text you write, the date, any mood tag, and any verse or prompt attached to the entry. Entries are stored on our server so they stay with you across reinstalls and so Eunice can read and respond to them if you're on Plus.
- Your prayers: the prayer list Eunice builds from what you tell her plus the ones you add yourself, including when you mark a prayer answered.
- Your Bible highlights and reading position: which verses you highlighted and where you left off, so the Bible opens where you were.
- Memories Eunice extracts from your conversations and journal: short facts, dated events, prayer requests, and notes about your growth areas. These are derived from what you say and are stored alongside your conversations.
- A push notification token issued by Apple, so we can deliver your morning verse and check-ins to your phone. It identifies your device to Apple's notification service, not to anyone else.
- Your Apple subscription status (the transaction identifiers Apple gives us), so we know whether Eunice Plus is active. We never see your card number, your Apple ID password, or your billing address. Apple handles all of that.
- Technical logs: timestamps, message counts, AI token usage, and error logs, kept so we can keep the service running and keep costs sane.
We do not collect your phone number, contacts, location, photos, or anything else from your device. There is no account and no password; the app identifies itself to our server with a random install identifier stored on your phone.
How we use it
- To generate Eunice's replies, your morning message, and her weekly reflection.
- To remember what you've shared and follow up on it.
- To let Eunice read and respond to your journal entries, if you're on Plus.
- To keep your journal, prayers, highlights, and reading position in sync so they survive a reinstall.
- To send push notifications at the times you chose.
- To check your subscription status.
- To run a safety check on each message before Eunice replies (see "Crisis policy" below).
- To fix bugs and understand aggregate usage (how many messages per day, how much the AI costs us). We look at aggregates, not at your individual conversations or journal, unless you ask us to help with a specific problem.
Eunice is AI
Eunice's replies are generated by a large language model. She is not a person, a pastor, a counsellor, or a medical professional. We say so in the app, on our website, and Eunice will tell you herself if you ask. Her answers can be wrong. Please treat her as a companion, not an authority.
Who else sees your data
We don't sell your data. We don't share it with advertisers. We don't show ads. The only third parties that touch it are the services we need to run Eunice:
- Anthropic, whose Claude models generate Eunice's replies. Your messages, the memories Eunice has about you, and (on Plus) your journal entries are sent to Anthropic's API to produce each response. Under Anthropic's commercial terms, API data is not used to train their models.
- Apple, for push notifications and for processing your subscription.
- Our hosting provider, where our server and database run.
The Bible itself (World English Bible and King James Version, both public domain) is bundled inside the app. Reading it, searching it, and highlighting it happens on your phone; only your highlights and reading position are sent to our server so they can be kept for you.
We will disclose information if the law genuinely requires it. If that ever happens we will tell you unless we are legally prevented from doing so.
Crisis policy
Before Eunice replies to any message, an automated check looks for signs that you may be in danger: self-harm, abuse, or an emergency. If it sees one, Eunice sets aside the devotional conversation and responds with care and practical help, including the 988 Suicide & Crisis Lifeline and 911 in the United States, or an equivalent line for your country. We may log that a crisis response was triggered so we can review how well it worked. We do not contact anyone on your behalf.
Deleting your data
You can delete everything from inside the app: Settings → Delete everything. After you confirm, we erase your name, settings, conversations, journal entries, prayers, highlights, memories, and push token from our database. It is immediate and we cannot undo it. Server backups that include your data are overwritten within 30 days.
Deleting your data does not cancel an Eunice Plus subscription, because Apple manages that, not us. Cancel it in iPhone Settings → your name → Subscriptions. You can also email us at dalynbutler@gmail.com and we will delete your data by hand.
How long we keep it
For as long as you use Eunice. If you stop opening the app, we delete your conversations, journal, prayers, highlights, and memories after 12 months of inactivity. Technical logs are kept for up to 90 days.
Security
Data travels over HTTPS and sits in a database on a server only we have access to. No system is perfectly secure, and we're a small team, so please don't share things in Eunice that would be catastrophic if leaked — for example passwords, card numbers, or someone else's private medical details.
Children
Eunice is for people 17 and older. We don't knowingly collect information from anyone younger. If you believe a child has been using Eunice, email us and we'll delete the data.
Your rights
Wherever you live, you can ask us what we hold about you, ask us to correct it, or ask us to delete it. Email dalynbutler@gmail.com. If you're in the EU, UK, or California, you have additional statutory rights, and we will honour them.
Changes
If we change this policy in a way that matters, we'll tell you in the app before it takes effect. The date at the top always shows the current version.
