Privacy Policy

01Who and what this document covers

My name is RusJJ. I am a single developer, not a company. On Google Play my apps are published under the developer name RusJJ-Apps. There is no company and no marketing department behind that name: there is one person who writes the code.

This policy covers every Android app published under the name RusJJ-Apps, and it applies the same way to users in every country.

Apps may differ from one another: one has analytics, another does not. So this document describes the maximum an app may do, while the exact answer for a particular app is given by the Data safety section on its Google Play page. I fill that section in myself, and it has to match what the app actually does.

This policy does not cover third party websites and services linked from the apps, nor modifications written by other people: those have rules of their own.

02What data is collected

What may be collected in some apps: crash reports, anonymous analytics, data used to show ads, technical data from network requests. This information is anonymous and cannot identify you as a person. What a particular app collects is always listed in the Data safety section on its Google Play page.

No app requests or receives:

• your name, email address, phone number or any other contact details;
• your contact list, messages, calls or calendar;
• photos and media beyond what you pick yourself inside the app;
• your precise location;
• the contents of your files and documents;
• your list of installed apps or your browsing history.

Registration and sign in are never required, because there are no accounts at all. The technical information an app may collect is covered one item at a time in the sections below.

03What stays on your device

The apps work locally and create ordinary working files on your device:

• settings and the options you chose;
• files the app needs in order to run: cache, temporary and working files;
• error logs, if the app keeps any.

This data never leaves the device: I cannot see it and I have no access to it. It is deleted when you clear the app data in Android settings or uninstall the app.

Note that if Android backup is enabled on your phone, such files may end up in your backup on Google Drive. That is an operating system feature and is governed by Google rules, not mine.

04Android permissions

An app may ask the system for permissions it cannot work without, for example file access, so that it can read or save the data it needs.

Every permission is requested only for the feature that needs it, and is used on the device. No permission is ever used to gather information about you personally.

The full and always current list of permissions for a given app is visible on its Google Play page and in Android settings. Any permission can be revoked in system settings: some features may stop working, but nothing else will happen.

05Crash reports may be used

A crash report is created only at the moment an app crashes, and exists for exactly one purpose: to find the cause of the crash and fix it.

Such a report contains technical information: device model, Android version, app version, interface language, call stack and error type.

A report does not contain your name, email address, contacts, location or the contents of your files.

Crash reporting is not enabled in every app. Where it is enabled, the Data safety section on the app Google Play page shows it as "Crash logs".

06Anonymous analytics may be used

Analytics shows which features people use and where they get stuck. These are events along the lines of "such and such screen was opened", with no tie to you as a person.

What may be collected: app version, device model, Android version, interface language, screens opened and session length.

Not collected: name, email address, contacts, precise location and file contents. I cannot link these events to a specific person, and I do not try to.

Analytics is not enabled in every app. Where it is enabled, the Data safety section on the app Google Play page shows it as "App interactions".

Where analytics is enabled, I plan to add a switch to the app settings that turns it off completely.

07Advertising may be used

Some apps may show ads. When they do, the ad network receives the advertising ID of the device, your approximate country and technical details about the device in order to pick an ad.

Nothing beyond that reaches the ad network: not your name, not your email address, not your files. I do not collect or store advertising data myself.

You can reset or delete the advertising ID in Android settings, under Privacy, item Ads. Ads will become less relevant afterwards, but the app will keep working.

Whether a particular app shows ads is visible on its Google Play page.

08Network requests and updates may be used

An app may use the network: check whether a new version exists, download files, or open links that you tap yourself.

On any network request the receiving server sees the IP address, the device type and the time of the request. That is an unavoidable part of how the internet works, not a separate act of data collection.

If the request goes to my server, this information lands in the standard web server logs. I use them only for diagnostics and for protection against abuse, I do not link them to anyone in particular, and I pass them to no one.

Requests to third party services, GitHub for example, are governed by the policies of those services.

09Sharing with third parties

I do not sell, rent out or hand over user data to anyone.

Where crash reports, analytics or ads are enabled, the technical information is processed by the provider of that service. Those are the only external recipients, they are named in the sections above and in the Data safety section of the app on Google Play. No one else receives anything.

There is one exception: the law. If an authorised state body demands data through the proper procedure, I have to comply.

10Google Play and Data safety

The apps are distributed through Google Play. The store itself collects its own statistics: install counts, country, device model, ratings and reviews. I only see it in aggregated, anonymous form, and individual users are not visible to me.

That collection is performed by Google rather than by the app, and it is governed by the Google Privacy Policy. If you install from another source, these statistics are not collected at all.

Every app on Google Play has a Data safety section. That section is the precise answer to the question of what this particular app collects today. I fill it in myself, and it cannot disagree with this document.

11Children

The apps are not directed at children and contain no features aimed at a child audience.

I do not knowingly collect data from children. If you believe a child has sent me any information, write to me and I will delete it.

12Storage and security

The most reliable way to protect data is not to collect it. I have no server holding your personal data, so there is nothing to break into and nothing that could leak.

The data an app stores on your device is protected by the Android operating system itself: other apps have no access to it.

Technical information, where it is collected, travels over an encrypted connection, is stored by the service provider, is used only for diagnostics and development, and is deleted once the retention period set by that service expires.

13Your rights and data deletion

You have the right to know what is collected about you, to receive a copy of it, and to demand its deletion.

I hold no personal data that could identify you, so as a rule there is nothing to request and nothing to delete. Technical information is anonymous and is not tied to an identity.

To remove everything connected with an app it is enough to uninstall it or clear its data in Android settings. No request to me is needed for that.

If you have a question or a demand regarding data, write to me at the addresses in the last section. I answer personally, there is no support team.

14Changes to this policy

This document may change, for example when an app gains a new capability.

On any substantive change the date at the top of the page is updated. The current version always lives on this page, and it is this address that is listed on Google Play.

The wording here describes the maximum an app may do, so the document stays accurate even while a given capability is not switched on yet. What an app actually does today is always stated in the Data safety section on its Google Play page.

15How to reach me

Questions about this policy, about data or about the apps go straight to me. I answer personally, usually within a few days.
