"Nothing leaves the house" would be a nice thing to say, but it wouldn't be true, so here is exactly what stays home and what doesn't.
Stays at home
| What | Where it's processed | Kept? |
|---|---|---|
| Your voice | On the computer the speaker is plugged into | No. Only the text of a request goes on to the Hive. |
| Voice prints | On the Hive | A small number, not a recording. Kept out of backups; anyone can ask her to forget theirs. |
| Her thinking | The language model on the Hive | Conversations aren't sent to any AI company. |
| Her memory | A database on the Hive | Yes, at home only. Secrets are never stored, and old items are cleaned up on a schedule. |
| Camera recognition | On the Hive | Pictures are never saved, and face data is never backed up. |
| Family chat | On the Hive | Yes, at home. Gift lists and unsent love notes are private to their writer. |
| Backups | At home | Encrypted. |
Leaves the house (and why)
| What | Goes to | Why |
|---|---|---|
| Web look-ups | A search service | Only the search words, after privacy guards strip personal details. An offline encyclopedia answers many questions without going out at all. |
| Weather and warnings | Public weather services | The home's general area, to get the forecast. |
| Phone notifications | Apple's notification service | That's how any app reaches an iPhone. Alerts are kept short. |
| Backup announcements | Amazon (Echo speakers) | When Nexus's own speakers can't play something, the text of the announcement can go through an Echo. |
| Music | Spotify and Amazon Music | Like any streaming request. |
| Phones away from home | An encrypted private network service | It connects family devices; the traffic itself stays encrypted end to end. |
| Family email | Google Workspace | Email is hosted, like most email. |
| This website | Cloudflare | It hosts the public pages. The family area sits behind a sign-in, and family photos have hidden data such as location removed. |
Promises
- Recordings of your voice and camera pictures are never kept.
- Voice prints are only made with that person's own OK.
- If location sharing between Jeremy and Candice is turned on, it needs each person's own yes on their own phone, and shared screens will never show who is where.
- The people who build Nexus never open private notes or gift lists, even to fix a bug.
