Privacy Policy

1. Who we are

Homie ("Homie," "we," "our," "us") is operated by Jonas and Stefan, based in Stockholm, Sweden. We are the data controller for the personal data described below.

For privacy questions or to exercise your rights, contact us via the contact form on heyhomie.tech.

2. What this policy covers

This policy applies when you:

• Install and run the Homie software on hardware you own (typically a Mac mini or a Linux server)
• Visit heyhomie.tech, welcome.hihomie.app, or related subdomains
• Use the household authentication service that we host on Cloudflare

It does not cover personal data held by third-party services you choose to connect (Google, Spotify, Twilio, OpenAI, Anthropic, Home Assistant, and others). Those providers act as their own controllers or as separate processors for you, under their own terms. The services we currently integrate with are listed in §6.

3. What we process, where it lives, and why

3.1 On your device

Homie is designed so that almost all personal data sits in a local SQLite database on the device that runs Homie (typically at ~/.config/Klaus/db/klaus.db or Klaus/db/klaus.db). We do not have access to this database.

Depending on which features you enable, this local database may contain:

• Household members: names, email addresses, phone numbers, dates of birth, roles, avatars
• Calendar data: events and reminders synced from Google Calendar (only if you connect it via OAuth)
• Messaging logs: iMessage, Telegram, and SMS messages that Homie reads or sends on your behalf
• Voice and conversation logs: transcripts of spoken interactions with Homie, with timestamps and which household member spoke
• LLM prompt and response logs: the prompts Homie sends to its language model and the responses received, with token counts
• Smart-home and music history: device states, songs played, automations performed
• Computer-action logs: records of automated actions Homie performed on your computer
• Memory: persistent notes about household preferences, routines, and members
• User-created content: contact lists, shopping lists, recipes, briefings, pantry inventory, gift ideas

This data stays on your device. We have no copy and no access. Its security depends on your operating system, your disk encryption, your backups, and who can reach the device.

3.2 In our Cloudflare infrastructure

To enable household signup and to coordinate authentication, a small amount of data passes through a Cloudflare Worker (auth.hihomie.app) and a Cloudflare KV namespace (homie_tokens):

• Household identifier and HMAC secret — a random ID per household and a cryptographic secret used to verify your daemon's requests. Stored while your household is active.
• OAuth tokens — when you connect Google Calendar, the OAuth refresh token is briefly placed in KV for your daemon to pick up. Auto-deleted after one hour or on pickup, whichever comes first.
• Member signup settings — when a new household member finishes signup at welcome.hihomie.app, the name, avatar, and calendar preference they entered are stored for up to one hour while the daemon picks them up.
• Open-invite claims — when you create a shareable signup link, the link metadata (slug, expiry, household reference) is stored until expiry. Default 24 hours, maximum 30 days.
• Member slugs — short identifiers used to keep member IDs unique within a household.

We process this data on the legal bases of performance of a contract with you (GDPR Article 6(1)(b) — operating the service you asked for) and our legitimate interest in running the authentication system securely (Article 6(1)(f)).

3.3 On our websites

heyhomie.tech and welcome.hihomie.app are static pages hosted on Cloudflare. They do not use analytics, advertising, or tracking cookies.

Cloudflare itself receives standard HTTP request information (IP address, user-agent, requested URL) as part of operating the network. We do not access individual visitor logs. See Cloudflare's privacy policy.

When you submit an invite link at welcome.hihomie.app, the data you enter (name, avatar, calendar preference) is stored as described in §3.2.

4. How long we keep your data

Local data on your own device is yours. We have no copy and cannot delete it for you. We recommend periodically reviewing what your local database stores, and deleting the SQLite file if you uninstall Homie.

5. Your rights under the GDPR

You have the right to:

• Request access to the personal data we hold about you (Article 15)
• Request correction (Article 16) or erasure (Article 17)
• Restrict or object to processing (Articles 18 and 21)
• Receive your data in a portable format (Article 20)
• Withdraw any consent you have given (Article 7(3))

Because most of Homie's data sits on your own device, you exercise most of these rights directly by editing or deleting local files. For the small amount of data held in our Cloudflare KV, email us via the contact form on heyhomie.tech and we will respond within 30 days.

You also have the right to lodge a complaint with the Swedish Authority for Privacy Protection (Integritetsskyddsmyndigheten, IMY) at imy.se.

6. Third-party services we connect to

When Homie communicates with the following services, personal data is sent to them and is governed by their own privacy policies. We list them here for transparency.

Transfers to processors located outside the European Economic Area (Anthropic, OpenAI, Twilio, and parts of Google and Cloudflare) are protected by the European Commission's Standard Contractual Clauses, and additional safeguards where applicable.

7. Children

Homie is designed for use by households and may be configured by adult household members to include children. We do not knowingly collect personal data from children under 13 without parental involvement. If you believe a child's data is being processed without appropriate consent, contact us via the contact form on heyhomie.tech and we will assist.

8. Security

All daemon-to-Worker communication is authenticated with HMAC-SHA256 signatures using the household secret. OAuth tokens stored in Cloudflare KV are short-lived and deleted on pickup. Local data security depends on your own operating system, disk encryption, and backup choices.

No system is perfectly secure. If you discover a vulnerability, please report it to us via the contact form on heyhomie.tech.

9. Changes to this policy

We may update this policy. Material changes will be reflected by the "Last updated" date at the top of this page and, where feasible, by a notice on heyhomie.tech.
