VoiceKey – Voice Screen Lock ("Application") is developed and operated by Alnico Tech Private Limited ("Company", "we", "our", or "us").
This Privacy Policy explains how we collect, use, process, and protect information when you use VoiceKey – Voice Screen Lock.
By using the Application, you acknowledge and agree to the practices described in this Privacy Policy.
1. Information We Collect
We aim to collect only the information reasonably necessary to provide the features of the Application.
Depending on the features you use, we may process the following information.
A. Account Information
You sign in to the Application with your Google account. We receive your name, email address and Google account identifier and keep them on our servers to run your account, restore your Premium subscription on another phone and answer support requests.
B. Voice and Microphone Information
VoiceKey needs microphone access to listen for the lock and unlock phrases you choose and, if you turn on Clap to Find, for claps or a whistle.
What you say is converted to text by your phone's speech recognition service (on most Android phones this is provided by Google, which may process the audio on its servers under Google's Privacy Policy). The Application receives only the text, compares it with your phrases on your phone, and does not record, store or upload your voice.
Clap and whistle detection runs entirely on your phone: the sound is analysed as it is heard and is never recorded or sent anywhere.
We do not use microphone access for unrelated purposes.
C. Phrases and PIN
Your lock and unlock phrases and your backup PIN are stored locally on your device and are never sent to us. The PIN is stored only in a scrambled (hashed) form.
VoiceKey does not create or store a voiceprint or any other biometric data.
D. Payment Information
Premium is a subscription paid through Razorpay using UPI AutoPay. Razorpay and your UPI app process your payment under their own privacy policies. We receive only the subscription and payment identifiers, amount, status and dates needed to provide Premium; we never receive your UPI PIN, bank account or card details.
E. Device and Technical Information
We may automatically collect limited technical information, including:
• Device model • Operating system and version • Application version • IP address • Device identifiers, such as the advertising ID and app instance IDs • Network information • Crash information • Diagnostic information • Application performance information
This information may be used to maintain, secure, troubleshoot, and improve the Application, and to measure our advertising (see section 11).
2. How We Use Information
We may use information to:
• Provide voice-based screen-lock functionality • Recognise your lock and unlock phrases • Run your account and Premium subscription • Enable and maintain security features • Improve Application functionality • Diagnose technical problems • Monitor Application performance • Measure the effectiveness of our advertising • Prevent misuse and unauthorized access • Provide customer support • Maintain the security of our services • Comply with applicable laws and legal obligations
3. Microphone Permission
VoiceKey requests microphone permission because it needs to hear your phrases and, if you turn on Clap to Find, claps or a whistle.
You remain in control of this permission and may grant or revoke it through your device settings.
If microphone permission is denied or revoked, voice-based features may not function properly.
Android provides system-level microphone indicators and privacy controls on supported versions of Android.
4. Screen Lock and Device Security
VoiceKey is intended to provide an additional voice-based security or locking feature.
The Application does not guarantee that your device or protected content will be completely secure against every possible method of unauthorized access.
Users should continue to use appropriate device security measures, such as a device PIN, password, pattern, biometric authentication, or other security mechanisms supported by their device.
5. Information Sharing
We do not sell your personal information or voice information.
We share limited information with service providers that help us operate the Application:
• Google (Firebase sign-in, analytics, crash reporting and notifications) • Meta Platforms (app events used to measure our advertising) • Razorpay (payments) • Amazon Web Services (our servers)
We may also disclose information where required by applicable law, legal process, court order, governmental request, or where reasonably necessary to protect our rights, users, property, or safety.
6. Third-Party Services
The Application may use third-party services, SDKs, APIs, or technologies for functions such as voice processing, analytics, cloud infrastructure, security, crash reporting, or other technical services.
These providers may process information according to their own privacy policies and applicable contractual or legal requirements.
We encourage users to review the privacy policies of relevant third-party services where applicable.
7. Data Storage and Security
We take reasonable technical and organizational measures to protect information against unauthorized access, misuse, alteration, disclosure, or destruction.
Your phrases and PIN are stored on your device, so their security also depends on your device's operating system, security settings, and physical security.
No method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.
8. Data Retention
We retain information only for as long as reasonably necessary to provide the Application's features, maintain security, comply with legal obligations, resolve disputes, prevent fraud or misuse, and fulfill legitimate business purposes.
Your phrases and PIN stay on your phone until you change them, another account signs in on that phone, or you uninstall the Application.
9. Data Deletion
You can request deletion of personal information associated with your use of the Application, including your account, in the Application (Profile → Delete account), at https://api.voicekeyapp.com/delete-account, or by writing to:
support@alnicotech.com
We cancel any active AutoPay first, then delete your profile (name, email), Premium status, device information and sign-in. We keep payment and subscription records without your name or email where tax and accounting law require them, and a one-way (hashed) form of your email address so that the introductory trial cannot be claimed twice.
Your phrases and PIN are removed when you uninstall the Application.
Certain information may be retained where required or permitted by applicable law, for security purposes, fraud prevention, dispute resolution, or legitimate business requirements.
10. Children's Privacy
VoiceKey is not specifically designed to knowingly collect personal information from children in violation of applicable law.
If you believe that a child has provided personal information to us inappropriately, please contact us at support@alnicotech.com so that we can review the matter and take appropriate action.
11. Analytics and Diagnostics
We use Google Firebase Analytics and Crashlytics to understand how the Application is used, identify crashes and improve it, and the Meta (Facebook) SDK to measure which of our ads lead to installs, trials and purchases.
These services may collect technical device information, Application usage events and device identifiers such as the advertising ID. You can reset your advertising ID or opt out of personalised ads in your Android settings.
12. Third-Party Links
The Application may contain links or references to third-party websites or services.
We are not responsible for the privacy practices, content, or security of third-party websites or services.
13. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes to the Application, our data practices, technology, or applicable legal requirements.
Any updated Privacy Policy will be made available through the Application or our website, together with a revised effective date.
