Puzzle #5 – "Is my data safer with Big Tech, a small app, or self-hosting?"
Big brands look polished and safe. Small apps look risky. Self-hosting sounds powerful but scary. This page helps you understand what really changes depending on who you trust with your data.
Why this is such a confusing question
People usually trust:
- familiar logos,
- slick interfaces,
- what friends use.
But real risk depends on:
- what data is stored,
- how it is stored,
- where it is stored,
- how the company makes money.
Laws like GDPR or CCPA give you some rights — like access, deletion, and information. But they do not mean "no data collection allowed." They do not automatically make every big company "safe" or every small app "dangerous."
Who should I trust?
The trust triangle: convenience, control, transparency
No option gives you everything. You are always balancing three things:
- Convenience: things work, sync, and auto-save
- Control: you decide what's stored and what's deleted
- Transparency: you can see and verify what's going on
• Big Tech → high convenience, low control, mixed transparency
• Self-host → high control, high transparency (if FOSS), low convenience
• Privacy apps → try to sit somewhere in the middle
How we describe trust on BestPrivacyApps
For each app in our directory, we highlight key trust questions:
- Where is the company based? (jurisdiction)
- Where is data stored? (data residency)
- Is it open-source? (and which parts)
- Has it been audited?
- How does it make money? (ads, subscriptions, donations)
- Can you export or delete your data?
- Does it support end-to-end encryption?
Quick check: who would you trust here?
You want to store encrypted personal journals. You are OK learning a bit of tech and prefer maximum control. What is the best direction?
- A) Big Tech notes app with ads
- B) Privacy-focused encrypted notes app
- C) Self-hosted encrypted notes on your own server
Correct answer: C
For very sensitive, long-term personal writing, running an encrypted tool yourself gives you the most control — as long as you handle backups and security well.
You need an email account to apply for jobs, log into services, and talk to non-technical family. You want better privacy, but you also need reliability. Which is the most realistic starting point?
- A) Only self-host your own email from day one
- B) Use a privacy-focused email provider with clear policies
- C) Keep everything on your old data-heavy email forever
Correct answer: B
Self-hosting email well is hard. A privacy-focused provider is a practical upgrade for most people.
You use a health or mood tracking app. What is the most important question to ask first?
- A) Does the app have dark mode?
- B) Does the app use my data for ads or sell it to partners?
- C) How many emojis does it support?
Correct answer: B
For highly sensitive data, you want to know if it is used for profiling, advertising, or sharing with third parties.
How we think about trust at BestPrivacyApps
There is no single "safest place" for all your data. Instead, we suggest a simple approach:
- Use privacy-focused apps for most daily things.
- Use Big Tech only where convenience truly matters and risk is low.
- Consider self-hosting for the few things that are deeply personal or critical.
The goal is not to be perfect. The goal is to choose where you want to be most independent.
