Every connection belongs to one of seven groups (mailbox, calendar, messages, social network, file storage, payments, other) and carries a disclosure sheet: what it may do, the route the data takes, what it costs, what the risk is — and how to end it again.

Connections

Seven groups, one disclosure sheet

The complete, searchable catalogue of every provider is on the “Connections” page — this page explains HOW the system behind it works: the grouping, checking instead of guessing, and what happens when you disconnect.

Three tiles from the “Connections” window re-enacted Re-enacted excerpt from the “Connections” window: a mailbox and a calendar show as connected, a Nextcloud file store shows as disrupted — each tile with its type and display name.

The seven groups

Mailbox
IMAP or Microsoft — several mailboxes are supported, one of them is the default channel.
Calendar
CalDAV, Microsoft or Google.
Messages
iMessage, Telegram — since 17 Sept 2026 WhatsApp runs via the browser, no longer through its own channel.
Social network
Facebook page, Instagram, LinkedIn, Mastodon, Bluesky.
File storage
Nextcloud.
Payments
Stripe — its own group instead of “Other”, so a payment connection stays visible as one.
Other
Anything that fits none of the other six groups — never guessed, always a fixed table by type.

Checking instead of guessing

For a long time Otto had no tool to check its own connection list — asked “can you find my mail accounts? if so, which ones”, it once listed three mailboxes, one of them entirely invented. Since then, the “show connections” tool reads the same table, unabridged and unfiltered, that the “Connections” window also takes its green dots from — with the explicit aside that foreign tool servers are NOT counted in it, because they live in a separate table.

The disclosure sheet

  • May

    What this connection may specifically read and write.

  • Data flow

    The route the data takes — straight to the provider, or via OCTOVO’s own server.

  • Cost

    Whether and what this connection itself costs, independent of the OCTOVO plan.

  • Risk

    What can happen in the worst case.

  • Ending it

    How this one connection is disconnected again.
