Encrypted doesn’t always mean equal.
We revisited Signal, Session, and Telegram to see how each really handles metadata, encryption, and storage in 2025.
It’s a reminder that convenience often costs visibility.

AI tools don’t just generate—they retain.
2025 saw major privacy shifts: Anthropic’s Claude now stores data for 5 years by default, OpenAI restored 30-day deletions, and Perplexity refined its opt-outs.
We break down how each platform treats your prompts, logs, and regions.

Note-taking apps are quiet risk hubs.
Few encrypt notes by default; some sync across borders without consent.
Apple Notes encrypts only in iCloud.
Evernote and Google Keep? No end-to-end protection at all.
Audit your syncs, disable analytics, and know where your thoughts reside.

IoT made offices efficient—and porous.
Printers, cameras, even thermostats send telemetry home.
Each is a data source waiting to be mapped.
Segment IoT traffic, limit outbound calls, and review vendor policies.
If it connects, it collects.

The October 2025 AWS outage reminded everyone: privacy depends on resilience.
When one region fails, cached data, rerouted endpoints, and fallback systems can create unseen exposure.
Multi-cloud, local backups, and encrypted logs aren’t luxury—they’re survival.

Privacy isn’t just about apps and data—it begins where your network meets the world.

Routers don’t read your data—encryption hides that—but they still log destinations and timing.
SMBs relying on ISP routers often overlook this visibility gap.
Audit firmware, disable telemetry, and encrypt DNS.
Switches, firewalls, and proxies matter too.

We published this one a while back, but it still hits hard. 🔐
Password managers promise safety—but they also concentrate risk.
If your team (or your future self) lives by a single vault, this is worth a reread.

💾 “Save as” isn’t neutral.
Filenames, timestamps, and hidden metadata can expose details you never meant to share.
Before encrypting or sharing, scrub file info, remove geotags, and use neutral naming.
Privacy isn’t just what’s inside the file—it’s what surrounds it.
