Effective August 27, 2026 ยท CozyChat 1.0
CozyChat
CozyChat is an iPhone client for AI agents that run through the CozyGateway server you choose. CozyLabs does not host your agents or ask for an account, email address, or password. Your gateway creates a device credential when you pair. That credential works with the gateway, not a CozyChat account.
Information on your iPhone
CozyChat stores your gateway address, display name, credential, certificate trust information and notification keys. Secrets use the iOS Keychain; preferences and conversation cache stay on your iPhone.
Choosing Forget gateway deletes the local gateway record, credential, trust record, and notification key. When you forget your final gateway, CozyChat asks the push relay to delete its registration. Local removal still completes while either service is offline.
Messages, agents, and photos
Messages, photos, conversation state and agent replies go to the gateway you paired. You choose and operate that gateway, including the AI models, providers, and other services configured with it. Those services handle information under their own settings and policies. CozyLabs does not host your gateway or receive, host, or retain its ordinary messages, photos, other media, conversation state, agent replies, or agent state.
| content | your gateway and services | CozyLabs |
|---|---|---|
| messages and photos | yes, under their policies | no |
| conversation and agent state | yes, under their policies | no |
| agent replies | yes, under their policies | no |
The iOS photo picker shares only the image you select. Before upload, CozyChat prepares it on your iPhone and strips location metadata.
Optional notifications
If you enable notifications, CozyChat sends Apple Push Notification service device tokens to the CozyLabs push relay. The relay returns an opaque registration identifier for each.
Ordinary notification bodies remain end-to-end encrypted: your gateway encrypts them before they reach the relay, which has no decryption key. The relay forwards the ciphertext to Apple and does not retain it.
| item | relay handling |
|---|---|
| notification body | encrypted by your gateway; forwarded to Apple without a decryption key or retention |
| APNs registration | active for up to 30 days; CozyChat refreshes after 21 days |
| source IP | held in memory while rate limits apply |
| ads and tracking | never used |
Live Activity relay requests are different. A request exposes only bounded generic lifecycle fields: phase, tool count, generic short status, and approval identifier. It does not include the prompt, draft, tool arguments or results, or reply content. The relay forwards the request rather than storing its payload.
Use of information
CozyChat uses this information to pair and authenticate your device, send conversations and notifications, perform requested actions, and restore local state. CozyLabs uses support-request details to answer you.
CozyChat includes no advertising or third-party analytics SDK. CozyLabs does not sell personal information or track you across apps and websites. Apple processes the technical information required to deliver notifications. Your gateway and its configured services use their own settings and policies.
Retention and your choices
- You control gateway-side messages, photos, agent history, and logs through the gateway and services you operate.
- CozyChat keeps local data until you forget a gateway, clear the applicable data, or remove the app. iOS may preserve Keychain items across reinstallations. Use Forget gateway before uninstalling if you want CozyChat to delete those items.
- The optional push relay retains active APNs registrations for up to 30 days. It deletes the final registration when the app unregisters it.
- You can decline notifications or disable them later in iOS Settings.

Security
CozyChat stores gateway credentials and notification keys in the iOS Keychain. It uses the secure transport and certificate trust behavior your gateway supports. Your gateway encrypts ordinary notification previews for your iPhone to decrypt. The gateway must read chat content to run the agent, so CozyLabs does not describe chat content as end-to-end encrypted.
No system removes every risk. Keep credentials, pairing codes, notification keys, and private transcripts out of support email.
Children
CozyLabs designed CozyChat for adults. Agents connected through your gateway may produce responses that do not suit every age. A parent or guardian should supervise a minor who uses the app.
Changes and contact
CozyLabs may update this policy when CozyChat, the notification relay, or legal requirements change. Check the effective date at the top for the current version.
