Mono — Privacy-First App Blocker
Effective date: January 2026 · Last updated: March 2026
This Privacy Policy describes how Mono ("we", "our", or "us"), developed and operated by Wbyte, handles — or more precisely, does not handle — information in connection with the Mono iOS application and the Mono Block NFC device (collectively, the "Service"). Privacy is not an afterthought for us. It is the architectural foundation of the Service. We have designed Mono from the ground up so that no personal data ever leaves your device. This policy exists to make that commitment explicit, transparent, and verifiable.
This Privacy Policy applies to:
It does not apply to any third-party websites, services, or applications that you may access through links present on our website. We encourage you to review the privacy policies of any such third parties independently.
Mono does not collect, store, or transmit any personal data or usage information whatsoever. This is not a legal caveat or a data minimisation claim — it is a statement of the technical architecture. We have not built any server infrastructure capable of receiving personal data from users, because doing so was never part of our design. Specifically, the Service does not collect:
There is no opt-in or opt-out mechanism for data collection because there is no data collection to configure.
In order to function, Mono stores certain configuration data locally on your iPhone. This includes information such as which applications you have chosen to block and your personal preferences within the app. This data:
You retain full ownership and control of this data at all times. Wbyte has no ability to access, modify, or delete it.
Mono uses Apple's Screen Time API (part of the Family Controls framework) to enforce app restrictions on your device. It is important to understand how this works:
Apple's own privacy practices governing the Screen Time framework are described in Apple's Privacy Policy, which is independent of this document.
The Mono Block is a passive Near Field Communication (NFC) tag that serves as the physical activation mechanism for focus sessions within the Mono app. The following statements describe its technical operation:
The Mono Block is intentionally designed to be a simple, stateless physical object. Its only function is to serve as a deliberate, physical trigger — reinforcing the intentional commitment that is central to Mono's philosophy.
Mono does not integrate any third-party SDKs, libraries, or services that collect, process, or receive data about you or your usage of the application. The following categories of third-party services are explicitly absent from the Service:
Because no third-party data processors are involved, there is no data sharing agreement to disclose, and no sub-processors to list.
Mono is designed in part as a tool for parental controls and is intended to be safe for use by, and on behalf of, children of all ages. Because Mono does not collect any personal data from any user — regardless of age — it is fully compliant with:
No parental consent is required for data collection purposes because no data is collected. Mono does not knowingly or unknowingly collect information from children or adults.
Under the General Data Protection Regulation (GDPR) and applicable data protection legislation, a legal basis for processing personal data is required. As Mono does not process any personal data, no legal basis is applicable. This section is included solely for transparency and completeness, and to confirm explicitly that there is no personal data processing activity to disclose.
Under applicable privacy laws, including the GDPR, you may have the right to access, rectify, erase, or port personal data held about you, as well as the right to object to or restrict processing. With respect to Mono:
If you have concerns about your rights or wish to submit a request, you are welcome to reach out via our contact page. We will respond to any inquiry in good faith and as promptly as practicable.
We reserve the right to update this Privacy Policy from time to time to reflect changes in applicable law, updates to the Service, or developments in our practices. When changes are made, the "Last updated" date at the top of this page will be revised accordingly. Significant changes will be communicated via App Store release notes accompanying the relevant update to the Mono application. We encourage you to review this policy periodically.
The foundational commitment of this policy — that Mono does not collect, store, or transmit personal data — will not be changed without explicit prior notice and, where required by law, your consent. Any version of Mono that departs from this commitment will be clearly identified as such before you are asked to accept it.
If you have questions, concerns, or requests related to this Privacy Policy or the privacy practices of Mono, please reach out via our contact page.
We aim to respond to all privacy-related inquiries within a reasonable timeframe. If you are located in the European Union and believe your data protection rights have been infringed, you also have the right to lodge a complaint with your local supervisory authority.
When you go Mono, you're set in stone — and your privacy is too.
