Frequently asked questions

The server computes a tier from votes and other signals: Observation (new or few votes), Soft trust, Confirmed, or Flagged. No human decides — it’s algorithmic. Higher tier means more unique voters, positive ratio, time span, and often geographic spread. See Trust Check and the extension for the result.

Domain or URL, email, phone number, IBAN, or any text. You enter the value; the system hashes it (no plain data stored) and shows community trust: plus/minus counts and tier.

A trust check + voting tool. You enter a label (domain/link/email/text), optionally pick a suggested label (Wikipedia/Wikidata), then see the current score and vote. Uses opaque IDs where possible; servers and WebSockets still coordinate SENDi! flows — see Privacy Policy for PII (Personally Identifiable Information). Use it from the Trust Check page or inside SENDi!.

Send a photo, file, link, text or voice once — continue only if you need to. Open SENDi!. Community SENDi! (reusable team link) — coming soon.

They are SENDi! now. Use /SENDi!/. Old /space/ addresses are gone. My Labels and Find Som stay as tools in the SENDi! menu.

SENDi! is the product. My Labels is your private map of SENDi!, devices, and Find names. Find Som rings and locates devices. All three live under the SENDi! menu.

Register a Find name on your device, then ring or locate it from another device — compass, map, and native alerts when the app is installed. Open Find Som or download from Downloads.

Your private map of SENDi!, devices, and Find labels — stored on your device. Optional encrypted cloud sync when you change phones (from €4.99/year). Open My Labels.

From Trust Check or the browser extension: after you see a result, vote +1 (trust) or -1 (warn). The extension sends an opaque client ID — no email or name. Rate limits apply (e.g. 5 votes per hour per IP).

Trust checks use hashes and aggregates where designed that way. We still run servers (APIs, WebSockets, logs) and optional telemetry with retention; the contact form can include PII (Personally Identifiable Information) if you type it. See the Privacy Policy for what is collected and exceptions.

Chat, video, and screen sharing in SENDi! often use P2P (WebRTC) when networks allow, but our servers still participate in signaling, join, session setup, and related APIs. Trust Check in a session coordinates over our WebSocket service when enabled. This is a technical description, not legal advice; see the Privacy Policy for PII (Personally Identifiable Information).

Yes. GET /trust?hash=... and GET /api/trust?hash=... return plus1, minus1, tier, totalVotes. POST /vote-hash accepts hash, vote, and an opaque clientId. See the project docs (API-PUBLIC-TRUST.md). For browser calls from another domain, the server may need to allow your origin (CORS).

Licensed team sessions have a max participants limit. If the session is full, the server rejects the join. Try a new SENDi! link or ask the admin to increase the limit.

From the homepage or Tools, open Extensions and pick your browser store (Chrome, Edge, Firefox, Opera). Developers can load the unpacked folder from the repo (Chrome/Edge: extensions/chrome-edge-opera/, Firefox: extensions/firefox/).
