Many apps we use daily request access to your camera, microphone, or location—and often bundle background analytics and tracking SDKs. But how many of us know exactly what is happening behind the scenes?

Privacy Inspector is an Android app designed to give you complete visibility and control over your device privacy and security—100% locally on your smartphone, with zero data ever sent to external servers.

🚀 Key Highlights & Benefits

• 📊 Clear Privacy Score (0–100): Instantly evaluate the safety of installed apps based on requested high-privilege permissions, background behavior, and bundled trackers.
• 🕵️ Ad & Analytics Tracker Detection: Reveal embedded tracking SDKs, telemetry frameworks, and ad networks hidden inside your apps.
• 🔄 Privacy Changes Timeline: Get notified when an update or a newly installed app silently introduces new sensitive permissions.
• 🧱 On-Device Firewall & DNS Filter (PRO): Block tracking domains in real time using a zero-cloud local VPN service—no traffic is ever routed through external servers.
• 🧹 Unused App Cleaner: Easily identify and clean up apps you haven't opened in months that still hold background permissions.

🔒 Zero-Cloud Privacy Guarantee

Privacy Inspector operates strictly on-device. No user account is required, no analytics are collected, and no personal data ever leaves your phone.

built a privacy focused yet productive clipboard manager few months back. zero-knowledge encryption, so even i can't see what people copy/paste. genuinely proud of it, thought it solved a real problem.

7 months later, less than 25 users on the chrome store. closed source the whole time.

took me a while to admit the actual issue. you can't ask people to trust a security tool from some random solo dev they've never heard of, with code they can't even look at. "trust me" isn't really a pitch when the whole product is about not having to trust anyone.

so, last week i made the extension's source code public. not open source technically, it's under Polyform Noncommercial 1.0.0, so nobody can fork it and resell it as their own, but anyone can read the code, verify the encryption does what it says, build it themselves if they want.

no idea if this fixes anything tbh. but felt like the honest move after building something people had no real reason to trust yet.

repo's here if anyone wants to poke around: https://github.com/encryptedclipboard/chrome-extension

not trying to sell anything, just wanted to put this out there since this sub gets the "built a thing, nobody came" feeling better than most places.

Hello World! I've been working on creating an encrypted messaging platform for the past year now and i would love to know your thoughts or opinions on it!

we have currently launched for Open-Beta testing!
the website is https://simplepgp.org/

It's entirely based around Simplifying the usage of PGP encryption for the average user as well as allowing for WebRTC calls, building communities and even hosting your own communities off of your own hardware / VPS using our Work-In-Progress FOSS 'Nodes' allowing for full customization and automation for uses like moderation, scripting and even building marketplaces / shops! Think of nodes as new-age Internet Relay Chats with a little bit better default encryption!

We also have emoticons that you can collect and trade with your friends which you can also use in chats, these animated icons are artist commissioned and they each have their own real-world value based on the reception of the community. :)

What's next for us?

• Android App Version (Still a little bit iffy on developing for Apple at the moment due to current privacy concerns)
• Constant development towards the Nodes FOSS clients (Should be able to release a working build by the end of August)
• Performance, stability, and security improvements

Feel free to check it out, give me any advice or recommendations for further features / updates!
Simple, Free, Welcome to SimplePGP!

I made this alone (with my friend Claude) and am the only person who worked on it, treat it with the skepticism that it deserves:

What it is: a Firefox extension that encrypts in the extension and decrypts messages in place, on whatever transport you're already using. Discord, Gmail, a forum, Reddit. It has no idea what site it's on and doesn't need to — the ciphertext is just text, so you paste it wherever you'd paste anything.

No account, no server, no network requests of any kind from the extension.

You and the other person exchange public keys directly, once.

Why I built it: the EU's Chat Control regulation would require messaging platforms to scan private messages before they're encrypted — on your own device, whether or not you're suspected of anything. You can't have both client-side scanning and end-to-end encryption; if a message can be inspected before it's sent, it was never private. This is a small working example of the other model: there's no server to mandate scanning at and no hook in the client for one.

How it works, briefly:

• Your identity is two keypairs (X25519 for key agreement, Ed25519 for signing), generated locally and never transmitted.
• You and a contact swap public keys over any channel — DM, email, read aloud over the phone. Doesn't need to be secret.
• Each message gets a fresh random key. The message is encrypted once with it; a copy of that key is sealed separately for each intended reader.
• There's no "to:" field. The sealed copies are anonymous blobs — your client finds yours by trying. An observer can't tell who the recipients are or how many are real.
• Every message is signed, so a group member can't forge one from someone else.

What it does NOT protect you from — please read this part:

• No forward secrecy. One shared key per contact, derived once, never rotated. Anyone who extracts your private key can read every message you have ever exchanged with that contact, including ones captured years ago.
• Your keys are protected only by your OS. They're non-extractable (extension code can't export them), but they sit unencrypted in a local SQLite file. Anything running as your user account can read them. There is no passphrase on the stored identity.
• Decrypted text is rendered into the page. A hostile or compromised site can read it while it's on screen.
• Metadata is fully visible. The platform still sees who you talk to, when, how often, and roughly how much.
• Nobody has audited this. It uses WebCrypto primitives rather than hand-rolled crypto, which rules out a whole class of mistakes, but that is not the same as being reviewed.

If you need protection from a determined, well-resourced adversary, use Signal. This is for putting a floor under the conversations that currently have none, on platforms you don't control.

Feedback: I am looking for feedback on 2 things:

1. The core idea, client side encryption agnostic about transport; how would you use it?
2. The user experience, I am a technical person and user experience and privacy does not alwayes go hand-in hand. What could I do to improve the user experience?

Looking forward to hear from you!

Lately I’ve been noticing more companies using Windows digital signage for dashboards, announcements, meeting room displays, and internal communication screens.

At first it looks simple, just connect a screen and display content. But once there are multiple screens across different locations, managing everything consistently seems like a bigger task than expected.

Things like remote updates, kiosk mode, content scheduling, and keeping systems stable probably become really important at scale.
