This community-driven approach ensures that F-Droid remains a platform that serves the interests of its users rather than commercial entities.
The significance of F-Droid lies not only in its role as an alternative app store but also in its commitment to fostering a community that values software freedom and privacy.
F-Droid’s Strict Inclusion Criteria
Ensuring the highest level of security and privacy, F-Droid has established a set of rigorous criteria for app inclusion. These criteria are designed to maintain the integrity and security of the apps available on the F-Droid repository.
Open-Source Code Requirements
F-Droid requires that all apps included in its repository have their source code openly available.

The Free Software Foundation and the Open Source Initiative recognize these licenses, which are essential for maintaining the principles of free and open-source software.
Anti-Features and Tracking Policies
F-Droid is stringent about anti-features and tracking within apps. It rejects apps that contain non-removable tracking or advertising libraries, or those that promote or depend on non-free services. This policy helps protect users from unwanted data collection and ensures a more private and secure experience.
By enforcing these strict criteria, F-Droid maintains a repository that prioritizes user privacy and security, making it a trusted source for secure app downloads.
Why is the PM mail client not on F-Droid?
ProtonMail, a popular email service focused on privacy, is notably missing from F-Droid, the well-known open-source app repository. This absence raises questions among users who prefer F-Droid for its commitment to open-source software.

ProtonMail developers have addressed the issue of their app’s absence on F-Droid. According to their statements, the primary reason is not due to a lack of effort but rather the complexities involved in meeting F-Droid’s stringent criteria.
“We have explored submitting our app to F-Droid but encountered several challenges that prevented its inclusion.”
The developers highlight that F-Droid’s requirements for apps to be entirely open-source, free from proprietary components, and compliant with specific licensing standards pose significant hurdles.
- F-Droid requires all apps to be open-source.
- Apps must be free from proprietary components.
- Compliance with specific licensing standards is mandatory.
Technical Incompatibilities with F-Droid’s Requirements
Delving deeper into the technical aspects, ProtonMail’s architecture includes components that are not entirely open-source, which directly conflicts with F-Droid’s inclusion criteria.
- ProtonMail’s use of certain closed-source libraries for specific functionalities.
- The requirement for F-Droid apps to adhere to strict anti-feature and tracking policies, which ProtonMail’s current architecture does not fully comply with.
These technical incompatibilities underscore the challenges ProtonMail faces in being listed on F-Droid.
Proprietary Components in ProtonMail’s Architecture
Understanding ProtonMail’s architecture requires examining its proprietary components. ProtonMail, known for its strong encryption and privacy features, has a complex infrastructure that includes both open-source and proprietary elements. This mix is crucial for understanding why ProtonMail is not available on F-Droid, a repository that strictly adheres to open-source principles.
Non-Open Source Elements in the Client
The ProtonMail client contains certain non-open source elements that are not compatible with F-Droid’s strict open-source requirements. One of the primary reasons is the use of proprietary libraries and APIs that are integral to ProtonMail’s functionality but are not publicly available for review or modification. These elements are crucial for ProtonMail’s user interface and certain advanced features, making it challenging to fully open-source the client.
Server-Side Closed Source Components
On the server side, ProtonMail also employs closed-source components that are vital for its operation. These components include proprietary encryption protocols and server management tools that are not available for public scrutiny. While ProtonMail has made significant portions of its code open-source, the server-side elements remain proprietary to protect ProtonMail’s intellectual property and maintain a competitive edge.
The presence of these proprietary components on both the client and server sides complicates ProtonMail’s inclusion in F-Droid. F-Droid’s policies require all apps to be fully open-source, making it difficult for ProtonMail to comply without significantly altering its architecture or licensing.
Business and Strategic Considerations
ProtonMail’s decision to exclude its mail client from F-Droid is influenced by various business and strategic factors. Understanding these considerations requires a closer look at ProtonMail’s commercial model and its implications.
ProtonMail’s Commercial Model vs. F-Droid’s Philosophy
ProtonMail operates on a freemium model, offering both free and paid services. This commercial approach allows ProtonMail to sustain its operations and invest in security and privacy features. In contrast, F-Droid is deeply rooted in open-source philosophy, advocating for free software and strict adherence to open-source principles. The divergence between ProtonMail’s commercial model and F-Droid’s philosophy may contribute to the incompatibility.
ProtonMail’s need to generate revenue through its premium services might be at odds with F-Droid’s strict policies against proprietary elements and anti-features. This fundamental difference in approach could be a significant factor in ProtonMail’s decision not to be listed on F-Droid.
Distribution and Update Control Preferences
ProtonMail prefers to maintain control over the distribution and updates of its client. By doing so, ProtonMail ensures that users receive updates directly from the source, potentially enhancing security and reducing the risk of modified versions being distributed. F-Droid, on the other hand, manages its repository with a focus on free software and strict vetting processes.
The difference in distribution strategies highlights ProtonMail’s preference for direct control, which may not align with F-Droid’s repository management practices. This misalignment could further explain why ProtonMail is available directly through its website and not on F-Droid.

Community Perspectives on ProtonMail’s Absence from F-Droid
The absence of ProtonMail from F-Droid has led to diverse discussions among privacy advocates and open-source enthusiasts. This discourse highlights the complex relationship between a privacy-focused email service and the open-source community.
Privacy Advocate Viewpoints
Privacy advocates have expressed mixed opinions regarding ProtonMail’s absence from F-Droid. Some argue that ProtonMail’s end-to-end encryption and privacy features outweigh its absence from F-Droid, making it a viable choice for those seeking secure email services.
Others, however, see ProtonMail’s absence as a significant drawback, citing the importance of being available through F-Droid as a mark of commitment to open-source principles.
Open-Source Community Reactions
The open-source community has also reacted with a range of viewpoints. Some developers appreciate ProtonMail’s efforts to provide a user-friendly, privacy-focused email client, even if it’s not available on F-Droid.
Others have criticized ProtonMail for not adhering strictly to open-source principles, particularly regarding the availability of its client on F-Droid.
This debate underscores the challenges faced by services like ProtonMail in balancing user needs, security, and openness.
Alternative Installation Methods for ProtonMail
For users eager to install ProtonMail, there are multiple avenues to explore beyond F-Droid. While F-Droid offers a secure and open-source app repository, ProtonMail’s absence necessitates looking into other installation methods.
Google Play Store Installation
One of the most straightforward ways to install ProtonMail is through the Google Play Store. The Google Play Store offers a user-friendly interface and automatic updates, making it a convenient option for many users. However, it’s worth noting that the Google Play Store version may include Google services, which could impact privacy.
Direct APK Download Options
Another method is to download the ProtonMail APK directly from the official ProtonMail website. This approach allows users to obtain the app without relying on third-party stores. It’s crucial to ensure that the APK is downloaded from the official source to avoid security risks.
Security Implications of Alternative Installation Methods
When choosing alternative installation methods, security implications must be considered. Installing from the Google Play Store may expose users to some tracking, while direct APK downloads can be risky if not done from a trusted source. The following table summarizes the security implications:
| Installation Method | Security Implications |
