privacy policy

effective march 30, 2026 · updated may 25, 2026

inner—stellar is built with the belief that your personal data — especially something as intimate as your birth details and life reflections — deserves real care. This policy explains exactly what we collect, why, and who else touches it.

We wrote this in plain language because we want you to actually understand it.

what we collect

When you use inner—stellar, we collect and store:

Account info — your email address and name (if you provide one), used for signing in and personalizing your experience
Birth details — your date, time, and place of birth, used to calculate your astrology and Human Design charts
Conversations — the messages you exchange with our AI guide, including any insights you save or pin
Charts — your astrology and Human Design charts, calculated from your birth date, time, and location
Focus areas — topics you tell us you want to explore (e.g. career, relationships, growth), plus any additional context you share about yourself
Creations — structured reflections, routines, or affirmations generated from your conversations that you choose to save
Waitlist signup — if you signed up on our website before creating an account, we collected your email address to notify you when the app launched

how your data is used

Your data is used for one purpose: giving you a personalized inner—stellar experience. Specifically:

Your birth date, time, and location are used to calculate your astrology and Human Design charts
Your conversations, focus areas, and chart data are used to provide relevant AI guidance
Your email is used to send you account-related messages (like a welcome email)

We do not sell your data. We do not use it for advertising. We do not share it with data brokers. Full stop.

third-party services

To make inner—stellar work, some of your data is processed by third-party services. We want to be transparent about this:

AI guidance — when you chat with your guide, your messages and chart data are processed by Google Gemini (routed through OpenRouter, an AI API gateway) to generate personalized responses. This data is sent through a secure API solely to provide your guidance — it is not sold and not shared with advertisers.
Chart calculations — your birth date, time, and location coordinates are sent to astrology-api.io (a Swiss Ephemeris-based astrology service) to calculate your astrology placements. Human Design calculations happen locally on our server. This data is necessary to generate accurate charts.
Location search — when you search for your birth city, the search query is sent to OpenStreetMap Nominatim, a free public geocoding service, to find coordinates.
Email — your email address and first name are shared with Resend (our transactional email provider) to send messages like your welcome email and password reset codes.
Backend infrastructure — your account data, charts, conversations, and saved insights are stored on Convex, our backend platform. Convex provides database, file storage, and authentication services.
Product analytics — anonymous behavioral data (which screens you visit, what features you tap, session length, retention patterns) is sent to PostHog, a product-analytics service, so we can understand what's working and fix what isn't. We never send your chat content, chart data, name, email, birth details, or location. Session replay is disabled. Events are tied to a random anonymous ID generated on your device. You can opt out by emailing hello@innerstellar.app.

We do not send your data to any services beyond those listed above. No ad networks, no data brokers.

data storage & security

Your data is stored on secure servers with encryption at rest and in transit (TLS)
Authentication tokens are stored in your device's secure keychain
All API keys and secrets are stored server-side — they are never exposed in the app

your rights & controls

You have full control over your data:

Export your data — you can export your conversations, insights, and profile information at any time from within the app
Delete your account — you can permanently delete your account and all associated data at any time. This removes everything: your profile, all conversations, all messages, all charts, all saved insights, and all creations. This action is irreversible.

When you delete your account, we delete your data from our servers. We cannot guarantee immediate deletion from third-party services that may have processed your data (such as AI model providers), but we do not retain copies ourselves.

what we don't do

We don't sell your personal information
We don't run ads or share data with advertisers
We don't access your camera, contacts, location, or calendar.
We don't share your email address with third parties for marketing

california privacy rights

If you are a California resident, you have the right under the California Consumer Privacy Act (CCPA) to:

Know what personal information we collect about you (this policy describes exactly that)
Delete your personal information — you can do this yourself from within the app (Blueprint tab → delete my account) or by emailing us
Opt out of sale of your personal information — this right is automatically satisfied because we do not sell your personal information and we never will
Non-discrimination — we will not discriminate against you for exercising any of these rights

To exercise these rights, email hello@innerstellar.app.
