Privacy policy

Updated 29 October 2026

FESTER is a daily ritual app for iPhone, made by Alyara Apps Studio LLC. This page says what FESTER keeps, why it keeps it, and how you remove it.

What you give FESTER

• Your sign-in: your Apple ID sign-in or your email address (see "Sign-in emails" below). If you use Sign in with Apple and hide your email, we get only Apple’s relay address.
• Your first name, which you enter during setup. FESTER shows it back to you and does not send it to Anthropic.
• Your birth date, birth time and birth city, and the city you live in now. FESTER uses them to find your birth star, your Moon sign and your dasha period. FESTER uses the city you live in now to find your sunrise.
• What you write in the app: your focus areas, your intentions, your evening check-ins and your reflections.
• Your recordings, only if you use “Say it” to record your daily line.
• A partner’s name and birth details, only if you add a partner. Your partner has no account and gives nothing through the app.

Why FESTER keeps it

To work out your chart and today’s sky, to write your daily line, and to keep your record of past days. FESTER does not sell your data, does not show ads, and does not track you across other apps or websites.

Where it is stored

Your account and what you write are stored with Supabase, our database provider, in the United States. The rules on the database let only your own account read or change your rows. Your recordings sit in a private storage folder that only your account can open.

Sign-in emails

If you sign in with your email address, FESTER sends you a sign-in code and link by email. The email comes from support@festerapp.com and goes through Google (Gmail and Google Workspace), our email provider. Google processes your email address and the message, which contains your code, so that it can deliver the email.

Writing your daily line

FESTER uses Anthropic’s Claude API to write your personal daily line and a rehearsal for an intention. Your phone sends a request to FESTER's server. The server sends the details to Anthropic and gets the text back.

• Your personal daily line is a FESTER Plus feature. FESTER sends today’s Moon day and phase, today’s Moon star, your birth star, your Moon sign, and the focus areas you chose. If you separately allow life season sharing, FESTER also sends a life season tag and two planet names, with no life season dates. FESTER writes a new Plus daily line after you allow AI writing, and checks your choices before sending life season details. It does not send anything you wrote, and it does not send your name, your email or your birth date.
• For a rehearsal for an intention, FESTER sends the wish you wrote and its life area after you allow AI writing and ask for a rehearsal. A wish is typed text sent as written, except that FESTER's server replaces angle brackets and line breaks with spaces, trims it, and sends at most the first 280 characters. Your phone sends an intention ID to FESTER's server for this request; the server reads the stored wish.

The selected date goes to FESTER's server to find or save the daily line, but is not in the text sent to Anthropic. FESTER does not add your user ID, name, email, birth date, birth time or birth place to the request.

Anthropic deletes API inputs and outputs within 30 days by default. Content flagged under Anthropic's usage policy may be kept for up to 2 years. Anthropic may keep data longer where the law requires, for feedback a person submits (5 years), or under other agreed terms.

FESTER keeps the line and the rehearsal in your account. Delete account removes FESTER's copy. You can turn AI writing off at any time in Settings, under AI writing. Turning this off also stops sharing your life season. Turning off AI writing stops new sends to Anthropic. Turning off AI writing or deleting your account does not itself remove data that Anthropic may still hold.

FESTER's server checks your AI writing choice before new sends to Anthropic. It checks both your AI writing and life season choices before sending life season details. The server table ai_consents keeps a consent record linked to your account: your user ID, consent kind, consent version, granted_at (when you allowed it) and withdrawn_at (when you withdrew it). Active consent is set when you allow. When you withdraw, withdrawn_at is set and the record stays. FESTER keeps this record until you delete your account.

Purchases

FESTER Plus is sold through the App Store. Apple handles the payment, and FESTER never sees your card details. RevenueCat, our subscription provider, receives your FESTER account ID, your purchase status and a random device-based identifier. Before you sign in, RevenueCat uses an anonymous identifier. RevenueCat also receives basic device and app details, such as the app version, so it can process your purchase. Our server asks RevenueCat whether your account has Plus before it writes your personal daily line. Deleting your account does not delete this record (see "Deleting your data").

Reminders

If you turn on reminders, your iPhone schedules them on the device. FESTER sends no push data to a server for this.

Deleting your data

Open Settings in the app and choose to delete your account. FESTER then removes your account, your chart details, your intentions, your reflections, your partner details, your recordings and your rehearsals. FESTER also removes your daily lines and your AI usage counts. FESTER also removes your consent record. You can also email us and we will do it for you.

Delete account does not remove your purchase records. RevenueCat, our subscription provider, keeps your FESTER account ID and your purchase history for FESTER Plus. This record does not contain your name or your email address. Apple also keeps its own purchase records, as Apple's terms and the law require. To ask RevenueCat to remove its record, email support@festerapp.com.

Children

FESTER is for people who are 18 or older. We do not knowingly collect information from anyone under 18. If you believe a person under 18 has given us information, email support@festerapp.com and we will delete it.

Changes and contact

If this policy changes, we update the date at the top of this page. Questions go to support@festerapp.com.
