Privacy Policy
Mustard Seed is an iPhone app run by Samarth Zalte, an individual in Los Angeles, California. Prayer is personal, so this policy is short and plain. Questions: support@mustardseedprayer.com.
Your first name
You enter it in the app. It is stored on your iPhone and in your private iCloud key-value storage. With each prayer request, it is sent to our server and to our AI provider so the prayer can address you by name. Our server does not store it.
What you type or say
If you speak, Apple’s speech recognition turns your voice into text. Where your iPhone supports it, this happens on the device. Otherwise Apple processes it under Apple’s privacy policy. Mustard Seed does not record or save your voice.
The text is sent to our server (hosted on Supabase, in the USA) and to our AI provider, Anthropic, which writes your prayer. We do not store the text after the request is finished.
Anthropic’s published policy for its commercial API, as we read it on November 14, 2026 (privacy.claude.com, last updated July 1, 2026; Commercial Terms):
- Anthropic does not train its models on content sent through the API.
- Inputs and outputs are automatically deleted from Anthropic’s backend within 30 days.
- If content is flagged for violating Anthropic’s usage policies, Anthropic may keep it for up to 2 years, and the trust and safety classification scores for up to 7 years. Retention can also be longer where the law requires it.
Anthropic can change these terms. Check its pages for the current policy.
Saved prayers, activity, reminders
Your saved prayers, your daily activity (which days you prayed or read), your reminder time and your topics are stored on your iPhone and synced through your private iCloud. That is Apple’s service, and we cannot access it.
Safety
The app checks what you write for signs of crisis, both on your device and on our server, so it can show help resources: 988, the National Domestic Violence Hotline, Childhelp and 911. Mustard Seed is not a crisis service.
Abuse prevention
To limit misuse we use an Apple App Attest key and count requests per day for each device or subscription. These are stored as a one-way keyed hash, with no name and no text. A quality log stores only a topic label and a match score, never your words.
Purchases
Apple handles purchases. RevenueCat processes your subscription status using an anonymous app user ID.
Analytics
We use TelemetryDeck, a privacy-focused service, for anonymized usage events, such as an onboarding step reached, a prayer made or the paywall shown. These events never include your words, your name or your prayers.
What we do not do
- No ads.
- No tracking across other apps or websites.
- We do not sell your data or share it for advertising.
Deleting your data
In Settings, Delete all my data removes everything from your iPhone and your iCloud. Subscriptions are managed in your Apple ID settings.
Children
Mustard Seed is not directed to children under 13, and we do not knowingly collect their information.
California residents
You may ask what personal information we hold, ask us to correct or delete it, and expect equal service if you do. We do not sell or share personal information as those terms are defined in California law. To make a request, write to support@mustardseedprayer.com.
Changes
If we change this policy, we will post the new version here with a new effective date.
