Privacy Policy

Updated: October 22, 2026

Tincall is an AI voice and text calling tool maintained by Chuli. The developer does not operate a shared chat, recording or model service. Data is sent to the services you choose and configure.

Information on your device

Contacts, connection settings, call transcripts, images, summaries and recordings you choose to keep can be stored on your device. API keys and access tokens are stored in the system Keychain. Recording is off by default; this does not disable real-time speech recognition or synthesis. Local request diagnostics may contain requests, replies and errors. They are not automatically sent to the developer. Review them before sharing.

You can choose a system contact's name and photo, or select photos for avatars, backgrounds or messages. Access requires your action and the applicable system permission or picker.

AI and cloud services you choose

Direct-model calls send enabled context, your current input and supported images to your configured model provider. The name you enter in your profile may be included in context. When raw-audio input is enabled, the current utterance is sent to a model that supports audio input.

Apple on-device speech recognition processes speech on your device. If you choose cloud speech recognition, that provider receives the audio needed for recognition. Speech synthesis providers receive the text to speak. MCP and backend modes send call input to the external platform or self-hosted service you configure.

These services may retain or process information under their own privacy policies and terms. Check their practices before connecting. Tincall cannot apply a single retention policy to user-selected providers.

If you enable a self-hosted cloud service, call text, images, summaries and recordings you authorize for synchronization are transferred between your device and that service. The cloud service is selected and managed by you. Its use does not give the developer operational access to your content.

Incoming calls and push notifications

To route incoming calls and Live Activities, the push sender processes service/user identifiers, device identifiers, push tokens, environment, device bindings, call and contact identifiers, call source, calling-access expiry and delivery status. Chuli maintains the official App Store version's push relay. Push payloads do not contain chat text, recordings, images or summaries.

Device bindings remain until removed or unbound. Delivery metadata is periodically deleted, normally after about seven days. Apple APNs, Cloudflare and any other sender you select may process network and delivery metadata under their policies.

Feedback email

Submitting feedback opens a mail composer with the app version, iOS version, device model and a feedback template. It does not send an email automatically or automatically attach chat history, recordings or complete request logs. You can edit the message, add screenshots or remove information before sending. Feedback sent to tincall@chuli.win is processed by email forwarding and email providers.

Purchases

The official App Store version uses Apple StoreKit for the free seven-day trial and one-time lifetime unlock. The app verifies transactions on your device and calculates access. If you enable incoming calls, calling-access expiry is supplied to the push service to prevent new calls after expiry. Tincall does not collect bank card numbers. Apple processes purchase, refund and transaction-verification information under its privacy policy.

Advertising and tracking

Tincall has no built-in advertising or cross-app tracking and does not sell user data to data brokers. The developer does not automatically upload call content, recordings or local request diagnostics for behavioral analytics. External services you choose process received data under their own policies.

Deletion, export and copies

You can delete local records, audio, images and configurations, stop synchronization or unbind a device. Deleting local data does not automatically delete exported files, copies retained by model or speech providers, your cloud copies or emails. Manage those copies with the corresponding service.

Contact

For privacy questions, data requests or feedback, email tincall@chuli.win. Review information before attaching private conversations, request logs or access tokens.

We may update this policy as features, service providers or legal requirements change. The date above identifies the latest revision.
