Read emails unobserved: How to protect yourself against tracking pixels in newsletters and Co.

Many services for sending newsletters use tracking pixels to analyze your behavior: Retrieval time of the e-mail, bounce rate, clicked links, location. Here you can find out how it works, why you should fight it and what you can do.

Ping. There's a newsletter coming into your digital mailbox. One click later you'll hopefully be a little smarter. In any case the senders of the newsletter are smarter after your click. They know at what time and where on earth you open the e-mail. They know which links from the newsletter you clicked on and which e-mail program you use. Depending on the newsletter service, you may know even more. Sounds creepy, but is everyday in email marketing.

Many professional newsletters are sent with the software of special service providers. They offer very different services. Tracking of the readers: inside belongs almost always to it. For some it's about being cheap. Others advertise with the fact that they can pursue visitors: inside with the help of individual tags also outside of the E-Mail on the web page of the sender. Still others make so-called A/B testing possible, with which similar target groups are presented different contents, in order to test for example the success of different formulations.

☣️ 1 pixel × 1 pixel = ∞ Tracking
Usually, these providers use HTML emails: that is, they embed the text to be displayed in HTML encodings so that the email becomes prettier and gets more design elements. Images can also be integrated via HTML code. The graphic can either be attached to the e-mail or downloaded externally.

Almost all newsletter services have in common the use of so-called "tracking pixels". They are integrated in the way described above via HTML codes and reloaded by an external server when the e-mail is opened. These tracking graphics are usually one pixel times one pixel in size or completely hidden. For each reader:in, a unique identifier is added to the graphic, which makes it possible to assign the behavior to individual profiles. A link could look like this:

https://newsletterversand.domain/trackingpixel.gif?identifier=123456789

Consequently, the server from which the pixel is loaded can analyze your behavior. A program stores on the server: When exactly was this link retrieved for the first time? And from where? From this it is also possible to determine which links from the newsletter you click on and thus also your more precise interests. The IP address is used to read out your supposed whereabouts.

Tutorial to have Google Classroom app run with microG

Goolag classroom for Android will work if you backup and restore the app data from a rom with gapps to a rom with microg

If you already have microg installed you can try this way:
- Remove microG if you have it
- Install a weebGapps magisk zip. Get one that suits your device from @WeebGAppsChannel (look out for the magisk tag!)
- Install Google Classroom and login with your account
- remove the WeebGapps Magisk zip (with Magisk Manager)
- Install microG again
- In Settings > Accounts, add your Google account (with microG)
- Done!

In other words:
Install GApps, login to Classroom, remove GApps, success
