Privacy Policy

Last updated: July 12, 2025

1. What stays on your device

Fixby runs an on-device AI model. The following data is created and stored entirely on your phone and never transmitted to any server:

• Conversations — all questions you ask and answers Fixby provides
• Voice recordings — speech-to-text runs on-device; audio is never uploaded
• Chat history — stored locally, deleted when you remove an appliance or your account
• AI model — downloaded once, runs locally

2. What leaves your device (and when)

Manual processing (one-time)

When you add an appliance, your manual PDF is uploaded to our servers for one-time processing by a cloud AI model. This processing extracts structured data (maintenance schedules, error codes, specs, safety warnings) that the on-device model uses to answer your questions accurately.

• The original PDF is retained on our servers, tied to your account, so it can be re-delivered to your device (e.g., for the in-app Manual viewer) without asking you to re-upload it. It is not shared with, or visible to, any other user or account
• The extracted structured data (the "bundle") is stored so we can deliver it to your device
• If another user uploads the same manual (matched by content hash), we reuse the existing bundle — this avoids redundant processing. The bundle itself contains no data about you and is not tied to your account
• Deleting your account or removing an appliance deletes your uploaded PDF from our servers (see Data retention below)

Authentication

Fixby uses Sign in with Apple and Google Sign-In. We receive and store:

• A unique user identifier (opaque ID from Apple/Google)
• Your email address (if you choose to share it)

We use this solely to associate your purchases and appliance list with your account.

Purchases

In-app purchases are handled entirely by the Apple App Store or Google Play Store. We store a purchase receipt to verify your entitlements. We do not process or store payment card details.

Activity logging

Fixby logs certain account actions (such as archiving and unarchiving appliances) on our servers for operational and audit purposes. These logs contain only timestamps, action types, and opaque identifiers — never manual content, conversation text, or personal information beyond your account ID.

Feature usage analytics

Fixby tracks which app tabs (Care, Ask, Fix, Manual) you use and how often, to help us understand which features are most valuable and improve the product. This data is content-free: it records only which tab was viewed, not what you asked or what was displayed. No third-party analytics SDK is used — this data is sent to and stored on our own servers only.

On-device AI model

The on-device AI model (~2 GB) that powers Care/Ask/Fix answers is downloaded once from Hugging Face's CDN over your device's own network connection. This download exposes your device's IP address to Hugging Face, not to Fixby — no manual, appliance, or conversation content is involved.

Fonts

The app's typefaces (Hanken Grotesk, JetBrains Mono) are served by Google Fonts, which exposes your device's IP address to Google the first time each font weight is fetched and cached on-device.

3. What we do not do

• We do not sell, rent, or share your personal data with third parties
• We do not serve advertisements
• We do not use third-party analytics or tracking SDKs (we collect minimal, content-free usage metrics on our own servers to improve the product)
• We do not collect device identifiers, location data, or browsing history
• We do not use your data to train AI models

4. Data retention

On-device data is retained until you delete it (by removing an appliance or deleting your account). Server-side data:

• Account data — retained while your account is active; deleted immediately when you delete your account in-app (or within 30 days if requested by email)
• Manual bundles — retained as long as at least one user has the appliance registered; orphaned bundles are purged periodically
• Archived appliances — automatically deleted 7 days after archiving, along with their uploaded manual PDF. Unarchiving within the 7-day window cancels the deletion
• Purchase receipts — retained as required by applicable tax and financial regulations
• Aggregate analytics (app performance, feature usage — never manual/chat content) — retained indefinitely for product metrics; when you delete your account, these events are disconnected from your account and appliance so they can no longer be traced back to you

5. Account deletion

You can delete your account at any time from Settings > Account > Delete Account in the app. If you cannot access the app, email support@fixby.app from the email associated with your account. See our account deletion page for full details.

6. Children's privacy

Fixby is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will delete it.

7. Changes to this policy

We may update this policy from time to time. Material changes will be communicated through the app or by email. Continued use of Fixby after changes constitutes acceptance of the updated policy.

8. Contact

If you have questions about this privacy policy or your data, contact us at support@fixby.app.
