Privacy Policy

Acharya is built by people who believe a birth chart is one of the most personal artifacts you can hand over. This policy explains what we collect, what we don't, and what we do with what we keep.

What we collect

Birth particulars

Name, date of birth, time of birth, and place of birth — for you and any family member you choose to add. We need these to cast a chart. Without them, Acharya can't read anything.

Conversation history

The questions you ask Acharya and the readings Acharya returns. We store this so you can revisit past conversations and so Acharya can remember context within your account.

Prediction feedback

When you mark whether a prediction played out (or didn't), we record that. This is how Acharya learns to be more accurate for you over time.

Account information

The email and authentication identifier from your sign‑in (Sign in with Apple or equivalent). We do not see your full Apple ID or any other personal information Apple chooses not to share with us.

Technical telemetry

Crash reports, performance metrics, and aggregate usage signals that help us fix bugs and improve the app. No conversation content is included.

What we don't collect

• We do not collect your contacts, calendar, photos, or location unless you explicitly grant permission for a feature that needs it (e.g., a future panchang‑aware calendar feature).
• We do not run third‑party advertising trackers.
• We do not sell, rent, or share your data with marketing partners. Period.

How we use what we keep

• To read your chart — birth particulars are passed to our astrological computation engine.
• To answer your questions — your chart and conversation context are passed to large language models we operate (Anthropic, OpenAI) under data‑processing agreements that prohibit those vendors from training on your data.
• To improve Acharya — aggregate, de‑identified signals (e.g., which kinds of questions are common, which features get used) inform product decisions. Your individual content is not used for model training.
• To recalibrate predictions — your prediction feedback informs how confidently Acharya makes claims to you. With your consent, anonymized feedback may contribute to cohort‑level calibration (the long‑run "Acharya Codex" project) — and you can opt out at any time.

Where data lives

Charts and conversation history are stored in a Postgres database we operate on infrastructure in the United States. Authentication is handled via Apple. LLM requests are made to Anthropic and OpenAI under business‑associate / data‑processing terms that bar them from retaining your prompts for training.

Your rights

• Access — you can request an export of everything we hold on you.
• Deletion — you can delete your account from inside the app. Charts, conversations, and feedback are removed from active databases within 30 days; backups age out within 90.
• Correction — birth particulars can be edited at any time inside the app.
• Opt‑out of calibration — your prediction feedback can be excluded from the cohort‑level calibration loop.

To exercise any of these rights, email hello@acharya.life.

Children

Acharya is intended for adults. Parents may add a child's chart to their own family graph; in that case the parent is the data controller for the child's birth particulars. We do not knowingly collect data directly from anyone under 13.

Changes to this policy

If we make a material change, we'll surface it inside the app and email you. The effective date above is updated whenever the policy is revised.
