You raise a very valid point. It is hard to trust regular marketing slogans blindly. The best way to verify these claims is to look for companies that make their client code completely open-source. When a provider puts their code on GitHub for everyone to see, it means independent developers can audit it for security flaws or hidden tracking mechanisms. Transparency is everything in cybersecurity. Personally, I always choose services that guarantee a hundred percent no-logs rule and back it up with open software. It is my go-to for safe browsing nowadays because I can actually see what the app is doing in the background. Another good sign is when a provider is based in a privacy-friendly jurisdiction. Just avoid free services because they almost always log your data to sell it to advertisers later. It is better to pay a small fee for actual peace of mind.
