What Avan keeps, and what it never does

• Your agent and everything it knows about you live on a private, per-user server volume that no other user can reach.
• We do not sell your data. We do not run ads. We do not track you across other apps or sites.
• You can delete your account from inside the app at any time — it destroys your agent and your data.
• The third parties involved are the ones that make the app work: sign-in, hosting, crash reporting, the AI model that generates replies — and the public book catalogs we query (book title and author only) to find cover art.

Avan is built by Avan Labs (Vu Bui), based in the United States. If you have a question about your privacy or your data, email support@helloavan.com. A real person reads it.

Avan only holds what it needs to be useful to you. In practice, that is:

• Account identity. When you sign in with Apple or Google, we receive a stable identifier and your email address so we can create and recognize your account. We use Supabase for authentication.
• Your reading life. The books you add, the ones you import (including a Goodreads CSV if you bring one), where you are in each book, and the notes and reading positions you build up over time.
• Your conversations. Your chat history with Avan, and any photos or screenshots you attach to a message — a page you photographed, a passage you screenshotted.
• The journal Avan writes. Avan keeps its own running diary about you and your reading. That diary is part of your private agent. It is for you, not for us — we do not read it to build a profile of you.

Each person gets their own agent, running with its own private storage volume. Your uploads, imported books, reading positions, and Avan's journal are stored on that per-user volume. It is isolated — one user's agent cannot reach another user's data.

Your chat history lives in two places: on that per-user volume, and in our application database (hosted by Supabase) — the database copy is what lets the app load your conversation history when you open it. Both copies are deleted when you delete your account.

The agent infrastructure runs on Microsoft Azure. We store what we need to run your agent and nothing we don't.

Avan is an AI agent, so generating a reply means sending the relevant parts of your conversation to a language model. We do this through OpenRouter, which routes the request to the model provider that produces the response. On our side, we send that content for one purpose only: generating Avan's reply to you. OpenRouter and the model providers it routes to process it under their own data policies — OpenRouter's is linked above.

We do not use your conversations to train our own models, and we do not sell them.

When a book lands on your shelf, your agent looks up its cover. To do that, it queries public book catalogs — Project Gutenberg's Gutendex, Apple Books, Wikipedia, and Open Library — and, if none of those have it, falls back to a web search. These lookups contain the book's title and author, nothing else: not your name, not your account, not your conversations.

To find and fix bugs, Avan can send anonymous diagnostic and crash reports through Sentry. In the main app this is controlled by a toggle in Settings → Privacy (“Send anonymous diagnostics”), which is on by default. You can turn it off at any time; the change takes effect the next time the app cold-launches. Crash reports are about app health, not about what you read.

One honest caveat: the Avan share extension — the small piece that runs when you share a book or screenshot into Avan from another app — currently sends crash reports whenever diagnostics are configured, independent of that toggle. We are working on extending the toggle to cover it.

• We do not sell, rent, or trade your data to anyone.
• We do not show you ads, and we do not share your data with advertisers.
• We do not track you across other apps or websites, and we do not build advertising profiles.
• Avan answers only to you. It does not work on anyone else's behalf using your data.

You can delete your account from inside the app — Settings → Account → Delete account. This is a full deletion, not a deactivation. Your account, your sign-in identity, and our database records about you — including your chat history — are deleted immediately. The same request tears down your agent and the per-user volume that held your uploads, imported books, reading positions, and Avan's journal; in the rare case a teardown step fails mid-flight, your agent is retired on the spot — disconnected from everything — and we finish removing it as an operations task.

Some routine, non-content operational records (for example, server logs or crash reports that have already been sent) may persist for a short time as part of normal system operation before aging out.

helloavan.com itself is hosted on Vercel. If you join the waitlist, the email address and answers you submit are stored in our Vercel-hosted storage so we can invite you and understand what you're hoping Avan will do. We use Vercel Analytics and Speed Insights to see aggregate, cookie-less traffic and performance data — they don't identify you or follow you to other sites.

Avan is not directed to children under 13, and we do not knowingly collect data from them.

If we change how Avan handles your data, we'll update this page and move the date at the top. Avan is early and evolving; we'd rather keep this page honest than freeze it.
