Who we are
DialAI: Caller ID, SMS & Block (the "App", formerly called myCaller) is developed and operated by AS3 Labs Global LLP (LLPIN ADC-8582), a limited liability partnership registered in India ("we", "us", "our"). This Privacy Policy explains what information the App uses, why, what leaves your phone, who it is shared with, and the choices you have.
Android package name: com.ai.caller.blocker
By installing or using the App you agree to this Privacy Policy. If you do not agree, please do not use the App.
On your phone first
DialAI is built to work on your phone. Your messages, call history and contacts are read and processed on your device and are not uploaded to our servers. The App keeps working without an internet connection; only the online features described below need one.
- We do not record calls.
- We do not upload the text of your SMS messages.
- We do not upload your address book or call history.
- We do not sell your personal data, and the App shows no ads.
Information processed on your device
Contacts
Used to show names and photos in the dialer, call history and messages, and for contact tools such as Private Contacts. Private Contacts are kept only on your phone, behind your PIN. If you export a Private Contacts backup, the file is saved where you choose.
Call log and phone state
Used to show your call history, identify incoming calls, apply your block list and Do Not Disturb rules, and power missed-call alerts, reminders, call notes, analytics and "best time to call". This stays on your phone.
SMS and MMS
When DialAI is your default SMS app, messages are stored and shown on your device. The App reads messages on your device to sort them (OTPs, bills, offers), find bill, EMI and recharge reminders, and warn you about likely scam messages. Message text is never uploaded. SMS are sent only when you tap send.
On-device AI
Scam-message warnings and the AI Brief (a short list of pending bills, payments, meetings and deliveries) are produced by small AI models that run entirely on your phone. When you mark a message as "scam" or "not spam", the App learns from it on your phone only. Nothing is sent to us or to any AI service.
Calendar (optional)
If you allow it, the AI Brief reads today's calendar events on your phone to show upcoming meetings. Calendar data is not uploaded. You can turn this off at any time.
Usage access (optional, Scam Safety)
If you turn on Scam Safety and grant Usage Access, the App checks which app is in the foreground only during a call, to warn you when a banking, payment or screen-sharing app is opened during a suspicious call. This information is not stored or uploaded.
Your photo and call screen background
Pictures you choose for your profile or call screen are copied into the App's private storage on your phone and are not uploaded.
Country
Detected on your device from your SIM and language settings to format numbers and enable region-specific features. We do not collect your location.
Information that leaves your phone
Caller ID and spam check
When you receive a call from a number that is not in your contacts, or when you look up a number, that phone number is sent to our server (Google Cloud Firestore) to check it against DialAI's community spam list. Your contacts and call history are not sent. When you are offline, the App uses only the information on your phone.
Spam reports
Numbers you report as spam are saved on your phone. If you are signed in, the reported number and the category you choose are also sent to our server so the community spam list can protect other users.
Account (optional, where available)
Some features may let you sign in with your phone number through Google Firebase Authentication. If you sign in, we process your phone number and an account identifier. Signing in is not needed to use the dialer, messages, blocking or AI features.
Rewards (India only, where available)
If a rewards programme is offered in your region and you join it, the call details needed to verify a claim (your number, the other number, call time and duration) and the payout details you provide (such as your name and UPI ID) are sent to our server to check claims, send payments and prevent fraud.
Diagnostics and analytics
- Crash reports (Firebase Crashlytics): device model, Android version, app version and the technical details of the crash, so we can fix bugs.
- Usage statistics (Google Analytics for Firebase): which screens and features are used, linked to an app-instance identifier, not to your name or number. We do not collect the Android Advertising ID.
- Notifications (Firebase Cloud Messaging): a push token for your device so we can send service notifications.
- App integrity (Firebase App Check / Google Play Integrity): checks that requests come from a genuine copy of the App.
App permissions
Optional permissions are requested only when you use the related feature, and you can withdraw any permission at any time in your device settings.

Google Play user data compliance
DialAI asks for SMS and Call Log permissions only when it is set as your default SMS app and/or default phone app, as Google Play policy allows for these handlers. SMS and call log data are used only to provide the App's calling, messaging, blocking and safety features, are processed on your device, and are never sold, used for advertising, or shared with third parties.
How we use information
- To provide the App's calling, messaging, caller ID, blocking and safety features.
- To maintain the community spam list.
- To fix crashes, improve performance and develop new features.
- To send notifications you have enabled.
- To detect, prevent and address fraud, abuse, security or technical issues.
- To comply with legal obligations and enforce our Terms.
Sharing and third-party services
We do not sell or rent your personal information. We share information only with service providers that help us run the App, under their own privacy terms, or when required by law.
| Service | Data it may process | Link |
|---|---|---|
| Google Firebase (Firestore, Authentication, Analytics, Crashlytics, Cloud Messaging, App Check) | Looked-up and reported phone numbers, account ID, usage events, crash logs, device model, Android version, app-instance ID, push token | Policy |
| Google Play Services | Device and app identifiers needed for app integrity and updates | Policy |
We may also disclose information if required by law, court order or a government authority, to protect our rights or users' safety, or as part of a merger, acquisition or sale of assets (in which case this policy will continue to apply).
Advertising
DialAI does not show ads and does not collect the Android Advertising ID.
Data retention
Data stored on your device stays there until you delete it, clear the App's data or uninstall the App. Phone numbers in the community spam list are kept while they are useful for spam protection. Account and rewards data are kept while your account is active and as long as the law requires afterwards. Crash and analytics data is kept according to Firebase's standard retention periods (up to 14 months), then deleted or anonymised.
Data security
Data sent to our servers is encrypted in transit (HTTPS/TLS) and protected by access controls. App data on your phone is kept in the App's private storage, is excluded from cloud backups where it is sensitive, and Private Contacts are protected by your PIN. No method of transmission or storage is completely secure, but we work to protect your data and will notify you and the authorities of a breach where the law requires.
Your rights and choices
- Permissions: you can deny or revoke any permission in Android settings, and turn off AI Brief, Scam Safety and AI scam warnings in the App.
- Access, correction and deletion: you may ask for a copy of the personal data we hold about you, or ask us to correct or delete it.
- Nominate: users in India may nominate another person to exercise their rights in case of death or incapacity, as provided under the Digital Personal Data Protection Act, 2023.
- EEA/UK users have rights under the GDPR, including objection, restriction and portability, and may complain to their local data protection authority.
- California residents have rights under the CCPA/CPRA to know, delete and correct personal information. We do not sell or share personal information for cross-context behavioural advertising.
To make a request, email contact@as3labsglobal.com with the subject "DialAI – Privacy Request". We may need to verify your request and will respond within 30 days.
Deleting your data
Most DialAI data is stored only on your device and is removed when you clear the App's data or uninstall it. If you have an account, you can delete it in the App under Settings → Delete account, where available. To request deletion of any data held on our servers (including spam reports linked to you), email contact@as3labsglobal.com with the subject "DialAI – Delete my data" and the phone number concerned. We will delete it within 30 days, except where we must keep it by law. Numbers reported by other users may stay in the community spam list.
Credits
The on-device scam-message model was trained in part on the SMS Spam Collection (Almeida & Hidalgo, UCI Machine Learning Repository), licensed under CC BY 4.0. No user messages were used to train it.
Children's privacy
DialAI is not directed to children under 13, and we do not knowingly collect personal information from them. Users in India under 18 must use the App with the consent and supervision of a parent or legal guardian. If you believe a child has given us personal information, contact us and we will delete it.
International transfers
We are based in India and our service providers may process data in other countries. Where data is transferred, we rely on appropriate safeguards such as the providers' standard contractual clauses.
Changes to this policy
We may update this Privacy Policy from time to time. We will change the "Last updated" date above and, for significant changes, notify you in the App. Continued use of the App after an update means you accept the revised policy.
