"Nowadays, with the Internet, any piece of knowledge can be accessed with minimal effort. What many fail to understand is the true cost of such capacity. Oftentimes, big tech firms such as Google and Facebook store user data and share them to other companies, in which they use to personalize ads. Many users are not aware of this considerable breach in user privacy."

Some of these shouldn't be trusted, including WhatsApp and Facebook Messenger, since they're owned and run by Meta/Facebook, whose business model requires them to collect as much information about you as possible. Read the article carefully to find the express guarantees of others. They exist.

There is a valid case that we the people are negligent about our health and that many of our short and especially long term illnesses could be prevented if we were. Since we are not required by law to be doing what we can to maintain and to improve our health to the extent reasonably possible to avoid both chronic and shorter term illnesses, however, the governments have failed to enact reasonable requirements to protect us from the pain and expense resulting. Simple exercise and nutrition requirements which are verifiable should be used to help determine whether or not the illness subject to insurance is actually caused by something outside of the reasonable control of the patient. Only in this case can the coverage actually fall under the general understanding of “Insurance,” which is meant only to compensate the injured for injury which is not their own fault. Punishing people arbitrarily for this collective negligence by cutting off necessary medical care in a way which creates profits, however, is not just, and those merely gaming the current legal system and medical establishment to maximize their gain through aggressive and abusive business practices are only exploiting the lack of enforcement of reasonable standards on the insured.
Those who accept their responsibility for their own health are already using digital technology to advance it and to prove both their efforts and their results.  The government's negligence creates opportunities for digital technology developers to support them, and such is a very socially responsible enterprise.  The main question, then, is how much value can we deliver to achieve the goals of developing training competence in the user and generally supporting their health building journey.

For the free version, explain to the user what the usual rules for handling their data are and how we can make money selling, leasing, or or otherwise engaging in business using it.

In the first level of paid, we give them dashboard level visibility of what we collect and time stamped event logs showing all transmission of any part of it.

In the next level of paid licensing, all transmission is off by default and they get the dashboard to view and analyze everything collected and stored on their device, along with notices of request for use of any part. At this level, they own and control all of the collected data pertaining to them.

The user pays for protection.

SQLite is a highly vulnerable db engine which produces files which can be easily read using Android's application interoperability features.  Therefore, all database files must be encrypted, including the block chained data change event record.  How does one execute SQL on an encrypted database file? The only way to access, navigate, filter, and apply analytics is to first read the entire file into RAM and decrypt it into custom maps and other feature convenient collections.  The security problem then is only how to securely store encryption and decryption keys.

User data collection is best done using a trusted forum to which only app users have access.  Like Stack Exchange, only private, it will provide a means of discussing use of the app, experiences applying its features, goals and strategies for achieving them, and can be a source of downloadable workout templates.  Rather than spying on users, collecting cell phone and other sensor data, acting ostensibly as their agent developing wonderful new technology, provide a means for users to share the information they want to share without fear of the usual "use this and you consent" webpage and app privacy policies which permit almost unlimited use of data collected in commerce.  Further, the user is engaged and knowingly contributing to the software's development.  Those that are so engaged form a core of supporters will benefit more, gaining more value from use of the software.

This is relevant to the design of a social media component into the exercise designer and tracker app so that users with a common constructive purpose can interact, share material, find support, etc.

The following is a comment I posted responding to this blog article:
How Social Media Shortens Your Life,

Your discussion of the problems with the current status quo of social media platforms is excellent and detailed, and as a software engineer I've both experienced the feeling of futility or lack of purpose that their "engagement" tactics produce, and spent a lot of time thinking about designing better. There are technology redesign solutions to the profitable and powerful social media platform designs prevalent on the Internet today, just a there are cooking and dining solutions to the prevalence of fast food and other convenience addictions. Governance of the user is the main problem since their rewarded goal generally is to attract attention with the most relevant or compelling content posts, and this frequently involves bending or breaking the ordinary rules of constructive restraint in social interaction.
By facilitating communities with constructive purposes, rather than collecting as many users as possible, with any motives or intentions possible, and mixing them all together into the same inflammable pot, you get an inherent governance from the users themselves. They are also not structurally motivated to attract the greatest number of followers or greatest amount of attention, but can if they like, and can simply be ignored, unlike algorithm driven attention grabbing scrolling machines. Search-ability by the user is key to finding content and other members with similar interests, and should be possible with user selected or provided criteria. This capability is crippled in profit driven or social manipulation driven algorithm control of content and ad delivery. Restore agency to the user and you restore civilization.

My proof of simultaneity (which Einstein argued was unprovable):
Pick one point in time. Prove two things happened.

Things might be much simpler than the experts on top would like us to believe.

Social interaction is impossible without common purpose, and prevalent social media designs create an algorithm driven statistical interaction control machine taking purpose out of our control.  This is justified as the normal way to enhance the user experience with relevant content, membership connections, and advertising.  Conveniently for the social media company's power, there is no search capability implemented allowing the user to do this for themselves, nor are they allowed to review what the sentiment analysis and other algorithms are basing their decisions on.
