Private by design.

Last updated · September 22, 2026

1. The Short Version

TAU's conversations and personal memory are stored locally on your device and processed by its on-device core AI. Vecorps does not receive those conversations or memories as part of normal AI processing. Limited account data is handled separately: we collect only what is needed to operate your account, including your email address. Subscription status is managed by Apple, as described below.

2. What We Collect

Account data (stored on our servers): your email address, a hashed password (we never see your actual password), your account creation date, and your authentication sessions. This is managed through our authentication provider (Supabase) with transactional emails delivered via Resend.

Waitlist email: if you ask to be notified when TAU launches, we collect the email address you submit on this website. That list is processed by Kit (ConvertKit). We only add you if you consent.

Subscription status: your Free or Pro status is managed by Apple through your Apple ID. We do not receive your payment details. Apple processes all payments.

Website hosting: this site is hosted by Vercel. Operating the site may generate ordinary technical logs, such as IP address and request metadata.

Website page views: we use Markorps, a first-party tool hosted at markorps.vecorps.com, to record which pages are opened and the referring site. It does not use cookies, advertising identifiers, or persistent visitor IDs. It does not run if your browser sends Do Not Track or Global Privacy Control.

What we do NOT collect: your conversations, TAU's memories about you, your name as shared with TAU, or any content of your interactions. These exist only on your device. We do not use advertising identifiers or sell any data.

3. Where Your Conversations Live

Conversations and personal memory are stored in a local database inside the app's private storage on your device, protected by iOS's app sandboxing. TAU's core AI runs locally on your device. Your messages are not sent to Vecorps servers for inference. After the one-time model download, TAU's current core experience works offline.

Because Vecorps does not receive or store your TAU conversation history or personal memory as part of normal AI processing, we cannot retrieve or provide a server-side copy of conversations or memories we do not possess.

4. Data Isolation

If a different account signs in on your device, the previous account's local data is erased first. Your memories are never accessible to another account.

5. Emails We Send

We send transactional emails only: verification codes and password reset codes, delivered via Resend. If you opt in to the launch waitlist, Kit (ConvertKit) sends that notice. You can unsubscribe at any time.

6. Data Retention and Deletion

Your account data is kept as long as your account exists. Deleting your account (Settings → Delete account) permanently removes your account data from our servers and erases all local data from your device. Local data is also removed if you uninstall the app. A waitlist email is kept until we send the launch notice or you ask us to remove it.

7. Model Download

On first launch, TAU downloads Qwen3-4B (~2.3 GB), an open-source language model, from a model repository. This download requests only the model files; your personal data is not transmitted.

8. Your Rights

Depending on your jurisdiction, you may have the right to access, correct, delete, restrict, or object to our processing of your personal data, and to request a copy of the personal data we hold. For a TAU account, you can view your email in Settings or delete it via account deletion. For a waitlist email, write to us and we will remove it.

If you are in the EEA, the UK, or Switzerland, you may also lodge a complaint with your supervisory authority. In France, that authority is the CNIL.

If you are in California, we do not sell or share personal information as those terms are defined under the CCPA / CPRA.

9. Children

TAU is not directed at children. We do not knowingly collect personal data from children.

10. Security

Account authentication uses industry-standard encryption in transit (HTTPS). Sessions are stored in the iOS Keychain. Local data is protected by iOS sandboxing and your device's security (passcode, Face ID).

11. Changes

We may update this policy. Material changes will be communicated in the app.
