Household apps
Budget, tax, car and a wall dashboard for one family: passkey sign-in, receipts by email, AI used for narrow jobs.
About
A set of private apps for one household, not offered as a service. They are here because they are where we prove the patterns we use for clients.
Budget (Apple Pay taps, bank statements and emailed receipts, sorted automatically), Tax (two people's returns kept apart the way the ATO does), Car (status, widgets and remote controls), Home (a wall dashboard: calendar, weather, lights, cameras, lists) and a family media requests page, among others.
What it does
- Face ID (passkey) sign-in; each person sees only their own data.
- Receipts sent in by email are filed by themselves, accepted only from known senders that pass DMARC.
- Apps share data only over the server itself, with their own tokens.
Security statement
- Passkeys instead of passwords; Face ID again before any car command; one-time guest codes stored only as hashes.
- Not public: every app needs sign-in, and none is indexed.
- Signed webhooks, upload limits, keys never shown back in full.
Shared platform measures (servers, backups, updates, monitoring) are on the Security page. Found a problem? security@emgee.dev.
Privacy statement
What it keeps
- The family's own records. No one else's.
Why
To run one household.
Where it is kept
On our server in Melbourne. Nightly encrypted backups (see Security); daily copies kept 2 weeks, weekly 2 months, monthly 1 year.
Who else sees it
| Service | What for | Where |
|---|---|---|
| Anthropic (Claude) | Reads receipts and sorts transactions, for the family only. Sent through the API, which Anthropic does not train on. | USA |
| Resend | Mail-in receipts and replies. | USA / Japan |
| Cloudflare | Delivers the site and blocks attacks; sees IP addresses and request details. | Global |
How long, and deleting it
Tax receipts kept 5 years, as the ATO requires; everything else until the family deletes it.
