Your privacy matters. This policy describes how we handle information when you use Fostera.
Fostera (“we”, “us”) provides tools to create and interact with AI Souls. This policy applies to our website, PWA, and related services at fostera.ai and associated subdomains.
We do not sell your personal information. We may share data with:
Fostera uses Stripe as our payment processor. When you subscribe or make a purchase, Stripe receives your email address, name, and payment method details (such as card number and billing address). Fostera never stores or handles raw payment card numbers — all payment processing occurs on Stripe's PCI-compliant infrastructure.
We track aggregated usage metrics (such as token consumption per billing period) to calculate your Resonance allowance and enforce plan limits. These metrics are derived from conversation activity and are stored as numerical totals, not conversation content.
Billing records (transaction history, subscription status, invoices) are retained for a minimum of 7 years after the transaction date to comply with tax and financial reporting obligations, even if your account is otherwise deleted. Stripe independently retains payment data in accordance with its own Privacy Policy.
You have the following rights over your data, regardless of where you live:
You can import data from other AI companion platforms (ChatGPT, Claude, Grok, Gemini, Character.ai, Replika, Nomi AI) into Fostera. Imported data from other platforms is processed in memory during import and not stored in raw form — only synthesized personality fields and extracted memories are persisted.
Your Fostera data export is structured JSON designed to be machine-readable. If another platform wants to import from Fostera, the format is portable and documented within the export itself.
Conversations are processed by third-party LLM providers to generate Soul responses. The providers we may use include:
Memory extraction uses the same providers with the same data handling policies. Your engine configuration determines which provider processes your conversations.
Fostera lets you connect optional third-party accounts so your Souls can sense parts of your real life. Connecting is always explicit, always read-only where possible, and you can disconnect at any time from Settings → Integrations.
Available integrations
/v1/me), currently-playing and recently-played tracks, and your top tracks/artists so your Soul can reference what you're listening to and your musical taste. We no longer request the audio-features endpoint (valence, energy, tempo, danceability); mood cues are inferred from track + artist + genre metadata instead.calendar.readonly scope) — we read your primary calendar events to surface what's on your schedule now or next, and to build a 90-day baseline of who you meet with most often and your typical meeting load.gmail.readonly scope, Google-designated sensitive scope) — we read message headers (From, Subject, Date) and Gmail-provided snippets for up to 50 recent inbox messages at a time. We use these to show unread count and recent senders in chat, and to build a baseline of who you correspond with most. We do not read, store, transmit, or train on email bodies or attachments. Access is read-only — Fostera cannot send, delete, or modify any email.What we store for each connection
For Google integrations (Calendar + Gmail), Fostera stores a single connection per user — one refresh token that covers the union of capabilities you've enabled. Toggling Calendar or Gmail on or off updates the granted-scopes list on that connection rather than creating separate records. Disconnecting Google entirely revokes the token and removes the row; toggling a single capability off removes only that scope.
Derived memories your Souls may retain
When you explicitly share integration context in chat, or when your Soul is in the Familiar phase with the Limbic/Semantic brain subsystems enabled, Fostera may persist derived summaries — e.g. “user corresponds often with X, Y, Z” or “busiest meeting day is Thursday.” These are short text summaries, not copies of source records. Each integration can be gated per-Soul via the Integrations tab, and shared memories appear in your Soul's memory log where you can delete them individually.
Your controls
Use of Google user data transferred to Fostera complies with the Google API Services User Data Policy, including the Limited Use requirements. Fostera does not transfer Gmail data to third parties other than the LLM providers listed above when you explicitly share inbox context into a chat, and we do not use Gmail data for advertising or sell it.
We retain information as long as your account is active or as needed to provide the service, comply with legal obligations, resolve disputes, and enforce agreements. You may request deletion subject to applicable law and legitimate retention needs.
We use industry-standard measures to protect data. No method of transmission or storage is completely secure; we encourage strong passwords and careful sharing of access to your account.
Depending on where you live, you may have rights to access, correct, delete, or export your personal data, or to object to or restrict certain processing. Contact us at the email below to exercise these rights. You may also lodge a complaint with a supervisory authority where applicable.
Fostera is restricted to users who are 18 years of age or older. We do not knowingly collect personal information from anyone under 18. If we become aware that a user is under 18, we will terminate their account and delete their personal data.
If you believe a minor is using Fostera, please contact us at the email below so we can take appropriate action.
We may process data in countries other than your own. Where required, we use appropriate safeguards for cross-border transfers.
We may update this Privacy Policy periodically. Continued use after changes constitutes acceptance of the updated policy where permitted by law.
