Overview

Tiles is currently alpha-quality software. It is usable for everyday tasks, though you may encounter bugs and performance issues. Tilekit, the developer SDK, is experimental, not a current priority, and intended for exploratory use, not production.

Tiles is designed so the default experience runs on-device. The local server binds to localhost, which limits exposed network surface during normal use. Configuration and application data live in standard local directories, and you can change the user data path when needed.

No. Application state is persisted locally with encryption at rest. The Rust build uses SQLCipher-enabled SQLite, and database connections use a passkey from secure storage. That raises the bar against casual inspection of copied files, though it does not remove all local risk.

Public identity is separated from private keys. Device and account identity use did:key identifiers from Ed25519 keys. Private keys and database passkeys are stored in the operating system’s secure credential store, not in plaintext app configuration files.

Peer-to-peer linking is user-mediated, not automatic. One device shows a ticket or local code; the other enters it and explicitly accepts or rejects. In release builds, endpoints derive from your stored secret key, and peer identity is checked against the delivered public key. Sync includes defensive controls, including a maximum size cap for downloaded deltas before they are applied.

Sync uses Iroh for device-to-device networking. When a direct path is not practical, Iroh’s public relays can help establish the connection; we list that relay use on our sub-processors page.

The product does not currently bundle obvious analytics SDKs such as Sentry, PostHog, Segment, Mixpanel, or similar telemetry. There is still local logging: the Python server may log request metadata and bodies to files under the Tiles data directory, so prompt content can appear in local logs unless logging changes.

Updates can check GitHub releases and install via the hosted installer script, which depends on release and hosting integrity rather than a stronger built-in end-user verification workflow. Dependencies are pinned and reviewed. The macOS package is code signed, notarized, and stapled. Bundled dependencies are self-contained so normal installation and use do not require live package downloads from the internet.

Use the published security policy and private disclosure path. Researchers can use GitHub Security Advisories or email security@tiles.run, with expectations for acknowledgement, triage, and coordinated disclosure. See SECURITY.md.
