Terms of Service

Last updated: July 27, 2026

By downloading, accessing, or using Vocis HD (the "App") provided by Gabriel Pincu, trading as sys32.net ("we", "our", "us"), you agree to be bound by these Terms of Service (the "Terms"). If you do not agree to these Terms, do not use the App.

1. Acceptance of Terms

By creating an account, accessing, or using the App in any manner, you acknowledge that you have read, understood, and agree to be bound by these Terms, as well as our Privacy Policy. If you do not agree to all of these Terms, you are not authorized to use the App.

2. Eligibility

You must be at least 13 years of age to use the App. By using the App, you represent and warrant that you meet this requirement. If you are under the applicable age, you may not use the App under any circumstances.

3. Account Registration and Security

You must provide a username and a display name to create an account.
Password requirements: Your password must be at least 8 characters long and include at least one uppercase letter, one digit, and one special character (e.g., !@#$%^&*).
You are responsible for maintaining the confidentiality of your password and login credentials.
You are solely responsible for all activity that occurs under your account, whether or not authorized by you.
You may not create multiple accounts, impersonate others, or use the App for any illegal or unauthorized purpose.
You agree to notify us immediately of any unauthorized use of your account at vocis@sys32.net.
We reserve the right to refuse service, suspend accounts, or terminate accounts at our sole discretion.
Account lockout after failed attempts: To protect against unauthorized access, your account will be temporarily locked for 15 minutes after 5 consecutive failed login attempts. During the lockout period, even a correct password will not grant access. This is a security measure, not a penalty — it prevents automated guessing of your password by malicious third parties. The lockout lifts automatically after the lockout period expires, or you may contact us at vocis@sys32.net for assistance.
You may change your password at any time while logged in via the in-app "Change Password" option.
Password recovery is not possible if you forget your password and are logged out. The App does not require or store an email address, phone number, or any other external contact information. This is a design choice for maximum privacy — if you forget your password while logged out, your account cannot be recovered and you will need to create a new account. You are responsible for saving your password securely.
If you forget your password and cannot access your account, you may create a new account and contact us at vocis@sys32.net to request deletion of your old account. To verify your identity, you must provide your old username and a list of your contacts from the old account. We will cross-reference this information against our server database. If the provided information matches, we will delete your old account and all associated data. We reserve the right to refuse deletion requests if identity cannot be sufficiently verified.

4. Acceptable Use — Prohibited Content and Conduct

You are solely responsible for all content you transmit, share, or otherwise make available through the App, including text messages, files, images, videos, and audio calls. You agree not to use the App to create, upload, share, or transmit any content that:

Sexually explicit or pornographic: Any content depicting or promoting nudity, sexual acts, sexual violence, or sexually suggestive material of any kind.
Harassing or abusive: Content that harasses, bullies, intimidates, threatens, or degrades others, including hate speech, cyberbullying, and personal attacks.
Exploitative or harmful to minors: Any content that exploits, abuses, or endangers minors, including but not limited to child sexual abuse material (CSAM). Such content will be reported to the appropriate authorities immediately.
Violent or threatening: Content that promotes, glorifies, or depicts violence, self-harm, suicide, or threats of physical harm against any person or group.
Harassment and stalking: Repeatedly contacting a user after being asked to stop, monitoring or tracking another user without their consent, or any form of cyberstalking.
Non-consensual intimate imagery: Sharing intimate or private images of another person without their explicit consent.
Hate speech: Content that promotes or incites hatred, discrimination, or violence against individuals or groups based on race, ethnicity, religion, gender, sexual orientation, disability, or any other protected characteristic.
Illegal activities: Content that facilitates, promotes, or engages in illegal activity, including fraud, illegal drug trade, human trafficking, or weapons trafficking.
Malicious content: Malware, viruses, ransomware, phishing links, or any other content designed to harm, disrupt, or gain unauthorized access to systems or data.
Evidence of violations: Because messages are end-to-end encrypted, users reporting violations are required to provide unencrypted evidence (such as screenshots or exported chat logs) to allow us to verify the violation before taking action.
Spam or solicitation: Unsolicited commercial messages, chain letters, pyramid schemes, or any form of unwanted solicitation.
Misinformation and impersonation: Impersonating any person or entity, or knowingly sharing false or misleading information that could cause harm.

By using the App, you acknowledge and agree that: You are solely responsible for the content you transmit. Violation of these Acceptable Use provisions may result in immediate suspension or termination of your account without notice, at our sole discretion.

5. Reporting Violations

If you encounter content or behavior that violates these Terms, please report it to us immediately at vocis@sys32.net. We will review all reports and take appropriate action, which may include removing content, suspending accounts, or reporting illegal activity to law enforcement authorities.

6. Encryption and Content Responsibility

Vocis HD uses encryption for all communications:

Key exchange: X3DH (Extended Triple Diffie-Hellman) with Ed25519 identity keys and signed pre-key signatures.
Messages: Double Ratchet (VocisMsg-v5) with AES-256-CTR + HMAC-SHA256, providing forward secrecy. Messages are deleted from the server immediately after delivery — nothing is stored long-term.
Files: AES-256-CTR + HMAC-SHA256 with per-chunk IV increment and per-file HKDF-derived keys from the Double Ratchet session. Files are deleted from the server after the recipient's first download.
Audio calls: WebRTC with mandatory DTLS-SRTP encryption. Audio is Opus-encoded (48 kHz, 192 kbps) and transmitted over UDP through our SFU relay server.
Local storage: All E2EE private keys are stored in an AES-256 encrypted database (SQLCipher) on your device, protected by Android Keystore. Keys are never written to disk in plaintext.

We cannot decrypt or access your messages and files. Messages and files are end-to-end encrypted — only the intended recipient can decrypt them. Audio calls use WebRTC with DTLS-SRTP, which is encrypted between the app and the SFU server. Because we cannot decrypt message or file content, we rely on users to report violations of these Terms. You are solely responsible for the content you send through the App. We do not proactively monitor, moderate, or decrypt user content. If E2EE encryption fails for messages or files, they are NOT sent — there is no automatic fallback to unencrypted transmission. Audio calls use WebRTC, which mandates encryption at the protocol level and cannot operate without it.

7. Intellectual Property

The App, including its code, design, branding ("Vocis HD", "sys32.net"), and all related intellectual property, is owned by Gabriel Pincu. You are granted a non-exclusive, non-transferable, revocable license to use the App for personal, non-commercial purposes in accordance with these Terms. You may not copy, modify, reverse-engineer, distribute, sell, or lease any part of the App.

8. Supporter Badge Purchases

Vocis HD offers optional Supporter Badges — consumable digital in-app products (bronze, silver, gold, and platinum) that users may purchase through Google Play Billing to support the development and operation of the App.

Digital goods only: Supporter Badges are purely digital cosmetic items. They grant no ownership rights, equity, or financial interest in the App or its operator. Badges do not affect core functionality (messaging, calls, encryption).
Consumable and cumulative: Supporter Badges are consumable products — they can be purchased multiple times. Each purchase adds to the user's lifetime support total, which determines their rank displayed in the Hall of Fame. Repeat purchases are intentional and allowed.
Pricing: Prices are displayed in the App in local currency and are set by us. Prices may be changed at any time for new purchases. Already-purchased products are not affected by price changes.
Payment processing: All payments are processed exclusively through Google Play Billing. We do not process, handle, or store any payment card information, billing addresses, or financial data. Refunds, chargebacks, and billing disputes are handled by Google Play in accordance with their policies.
No refunds by us: Because the products are digital and consumable, all purchases are final. Refund requests must be directed to Google Play. We will not issue refunds directly. Google Play may provide refunds at its discretion under its refund policy.
Purchases and account termination: If your account is terminated for violation of these Terms, any Supporter Badge purchases are forfeited. We do not provide refunds for terminated accounts.
Hall of Fame: Users who have purchased Supporter Badges may appear in the public Hall of Fame leaderboard, ranked by lifetime support total. You may contact us to opt out of the public leaderboard at vocis@sys32.net.

By making a purchase, you confirm that you understand and agree to these terms.

9. Limitation of Liability

The App is provided "as is" and "as available" without warranties of any kind, either express or implied. To the maximum extent permitted by law, Gabriel Pincu shall not be liable for any direct, indirect, incidental, special, or consequential damages arising from your use of the App, including but not limited to:

Service interruptions, delays, or unavailability.
Loss of data or communications content.
Unauthorized access to your account or data (except where caused by our negligence).
Actions taken by other users, including violations of these Terms.

10. Service Availability

We strive to provide reliable service but do not guarantee uninterrupted availability. The service may be temporarily suspended for maintenance, updates, or unforeseen circumstances. We are not responsible for any loss arising from service downtime.

11. Termination

You may delete your account at any time using the in-app "Delete Account" option. We reserve the right to suspend or terminate accounts that violate these Terms without prior notice. Upon termination, your data will be deleted in accordance with our Privacy Policy. If your account is terminated for a violation of these Terms, you may not create a new account. Creating a new account after termination constitutes a further violation of these Terms.

12. Governing Law and Dispute Resolution

These Terms are governed by the laws of Romania. Any disputes arising from these Terms or your use of the App shall be resolved by the competent courts in Romania. Nothing in these Terms affects your statutory rights as a consumer under Romanian or EU law.

13. Changes to These Terms

We may update these Terms from time to time. Material changes will be notified through the App. Continued use of the App after changes become effective constitutes your acceptance of the new Terms. If you do not agree to the changes, you must stop using the App and delete your account.

14. Entire Agreement

These Terms, together with our Privacy Policy, constitute the entire agreement between you and Gabriel Pincu regarding your use of the App and supersede any prior agreements or understandings.
