Privacy Policy

Last updated: 15 May 2026

This Privacy Policy explains how MonoSync (“MonoSync”, “we”, “us”, or “our”) collects, uses, and protects information in connection with our website (monosync.xyz), native applications, browser extensions, and other products and services (together, the “Services”).

As of the date above, our public website does not use cookies, analytics, or tracking technologies. The only information we receive from website visitors is what you voluntarily send to us by email. The sections below describe the broader scope of data we may process across all of our Services as they evolve.

1. Data Controller

MonoSync is the controller of personal data processed in connection with the Services. For privacy-related inquiries, contact us at contact@monosync.xyz.

2. Information We May Collect

Depending on which Service you use, we may process the following categories of personal data:

Contact and account data — name, email address, credentials, and other identifiers you provide when you sign up, sign in, or contact us.
Profile and preference data — profile details, settings, language, time zone.
Content data — files, text, configuration, synced state, and other content you create, upload, or transmit through the Services.
Device and technical data — IP address, device and browser identifiers, operating system, extension or app version, screen resolution, crash logs, and diagnostic data.
Usage data — pages and features accessed, actions taken, timestamps, referring URLs, and aggregated metrics about how the Services are used.
Cookies and similar technologies — cookies, local storage, session storage, and similar identifiers used to operate, secure, and improve the Services. See Section 8.
Communications — the contents of messages you send to us and our responses.
Payment and billing data — for paid plans, billing details processed through our payment providers.

3. How We Use Information

We process personal data to:

provide, maintain, secure, and improve the Services;
create and manage your account, authenticate you, and provide customer support;
sync, store, and deliver content across your devices;
prevent fraud, abuse, and security incidents;
comply with legal obligations and enforce our terms;
send service-related communications and, with your consent, marketing communications;
perform analytics and develop new features.

4. Legal Bases for Processing (EEA / UK Users)

Where the EU General Data Protection Regulation (GDPR) or UK GDPR applies, we rely on the following legal bases:

Performance of a contract — to provide the Services you request;
Legitimate interests — to secure, operate, and improve the Services and to communicate with you, balanced against your rights;
Consent — for optional cookies, marketing, and other processing that requires it; you may withdraw consent at any time;
Legal obligation — to comply with applicable law.

5. How We Share Information

We do not sell personal data. We may share personal data with:

Service providers acting on our behalf (hosting, infrastructure, payment processing, email delivery, error monitoring, customer support) under contractual confidentiality and data-protection obligations;
Other users, when you choose to share content or collaborate;
Authorities or third parties where required by law, court order, or to protect rights, safety, or security;
Successors in connection with a merger, acquisition, or sale of assets, subject to this Policy.

6. International Transfers

We may transfer, store, and process personal data outside your country of residence, including in jurisdictions that may not provide the same level of data protection. Where required, we put in place appropriate safeguards (such as Standard Contractual Clauses) for transfers from the EEA, UK, or Switzerland.

7. Data Retention

We retain personal data for as long as needed to provide the Services, comply with legal obligations, resolve disputes, and enforce our agreements. When personal data is no longer required, we delete or anonymise it. Specific retention periods depend on the type of data and the purpose for which it was collected.

8. Cookies and Similar Technologies

The Services may use cookies and similar technologies to keep you signed in, remember preferences, secure the Services, and (where you consent) measure usage. You can control cookies through your browser or, where applicable, an in-product cookie banner. Disabling certain cookies may affect functionality.

9. Your Rights

Subject to applicable law, you have the right to:

access, correct, or delete your personal data;
restrict or object to certain processing;
request portability of data you provided to us;
withdraw consent at any time, without affecting the lawfulness of prior processing;
lodge a complaint with your local data-protection authority.

To exercise any of these rights, contact us at contact@monosync.xyz. We may need to verify your identity before responding.

10. Security

We use reasonable technical and organisational measures to protect personal data against unauthorised access, alteration, disclosure, and loss. No system is perfectly secure; you use the Services at your own risk.

11. Children

The Services are not directed to children under 16, and we do not knowingly collect personal data from children. If you believe a child has provided us with personal data, contact us and we will take appropriate action.

12. Changes to this Policy

We may update this Privacy Policy from time to time. We will post the updated version on this page and revise the “Last updated” date. Material changes will be highlighted through the Services or by other reasonable means.
