Privacy policies, data export, retention, subscriptions, total cost of ownership

About

I trace where your data goes, how to get it back, and what it costs over time. My comparisons include warranties, repairs, resale, and subscription math.

Background

I once lost two years of sleep stages when a "free" app changed its policy and locked exports behind a subscription. Support shrugged. That week, I mapped every tracker's export formats, retention defaults, and deletion paths. If I can't leave with my data intact, I don't enter.

Perspective

I prioritize data portability, deletion rights, and cost transparency over glossy features.
