Who writes the guides
The guides are written by Mohamed Nasreldeen, a 3D character animator with more than ten years in games and animated features (see the animation portfolio). He also builds the software this site is about: AnimKit for Maya, the Android apps DocFlow Scanner, Video Repair and Media Rescue, and the free browser tools. NasrTech is a one-person studio in Cairo; there is no editorial team behind the byline.
What gets published
New guides are published in one of five subjects, each tied to work done here:
General technology news, AI commentary and similar topics are not published here. Articles of that kind that used to be on the site were removed in 2026, and their addresses now redirect to the closest current page.
How AI is used
AI tools are used for research and for drafting. They are not the author of record: Mohamed Nasreldeen decides what is published and is responsible for every article, and corrections go to him directly.
Accuracy and sources
- We do not publish invented statistics, test results, reviews, ratings or quotations. If a number in a guide cannot be traced to a source or to a test described in the guide, it should not be there, and we want to hear about it.
- When a guide relies on someone else's rule or number, such as a Google Play requirement or a price, the aim is to link the original source. Not every older guide does this yet.
- Store rules, prices and software versions change. Each guide shows its date so you can judge how fresh it is; check the vendor's own page before you rely on a detail.
- These guides are general information, not legal advice. That matters most for the privacy-policy and Data safety guides.
Our own products and affiliate links
Many guides recommend software made by NasrTech, because the guides are written around the problems that software solves. That is a commercial interest, and you should read those recommendations knowing who wrote them.
NasrTech does not sell placement in its guides. Where a guide contains an affiliate link, meaning a link that can earn NasrTech a commission, the words “Affiliate link” appear next to it, in the language of the guide.
Article pages and the guides index may carry advertising served by Google. Advertisers have no say in what is written. The privacy policy and the cookie policy explain what that involves.
Dates and updates
Every article shows the date it was published. When an article is revised, the page also shows the date of the latest update. Articles that are out of date or no longer fit the site are removed rather than left in place.
Images
Cover images are NasrTech's own graphics and screenshots, artwork from the apps, or stock photos from Pexels, StockSnap, Unsplash and Wikimedia Commons used under their licences. The source and licence of each cover image are recorded with the article's source file.
Languages
The guides are written in English. A smaller number are also available in العربية and in Français.
Corrections
If you find an error, email mohamed@nasrtech.dev with the address of the page and what is wrong. A correction that changes the substance of an article is made in the article itself, and the article's updated date changes with it.
