Read your own Facebook file. On your own device. Fast.
See what Facebook knows about you — in 2 minutes, free, on your own device. Nothing uploaded, ever.
See your ad profile, location history, removed friends, and raw login data from your Meta export file. Open-source scanner runs entirely in your browser — your data never leaves your device.
Nine on-device tools that actually work
One suite, your data stays yours. Every tool runs in your browser, is free to try, and is honest about what it costs — no upload, no account, no tracking.
DataVault — read your own Facebook export
Meta hands you your file — every message, photo, location, ad profile. DataVault opens that export on your own device and shows you what's in it. No upload, no account. The scan, your people, your timeline and full-text search are free; the deep analysis is one lifetime unlock.
Free — the core
- Open your export on-device
- People, timeline, full-text search
- Nothing ever uploaded
✦ Lifetime — £9.99 one-time
- Deep Dive — the red flags Meta never showed
- Relationship maps, every decade
- Advertiser audit · face clustering · location trail
- Keepsakes — Memory Book, colouring book, memory cards
Your export never leaves your device. Only the payment touches Stripe.
StreamForge — which income stream fits you?
Answer 10 questions and get a scored match across eBook & KDP publishing, affiliate marketing and mobile apps, with a playbook for your strongest. Honest up front: there is no fully passive income. On-device, nothing uploaded.
Free. A 10-question quiz, a ranked breakdown, a first-month playbook.
What's in your kitchen — cook what you have
Type the ingredients you've got and get recipes you can cook now, matched against your list. Pantry staples always count, missing items get a swap. Classic Indian recipes, conversions, step timers, hands-free cook mode. On-device, nothing uploaded.
Free. Matches, swaps, converts, scales and cooks — all in the browser.
Transition Kit — passwords, with dignity
If a parent keeps resetting and forgetting passwords, a vault won't fix it — the transition will. A free, printable 20-minute plan: recovery line, one shared vault, the routine for when she resets, and dignified scripts instead of fibs.
Free. Printable, on-device, based on what caregivers actually do.
Tai Chi Walking — balance, step by step
The mindful heel-to-toe walk most recommended for older adults. Full technique (the "empty foot" principle), evidence-based benefits, foot-placement diagrams and follow-along videos. Free, on your device, nothing uploaded.
Free. Watch the videos, follow the steps, walk like a cat — anywhere.
ClearTalk — speak clearly, 5 min a day
Clear speech is a skill that warms up like a muscle. A guided daily trainer: a 5-minute warm-up, sound drills for the sounds you want sharper, and four conversation-level habits. On-device, no account — a gym, not a doctor.
Free. On-device, no account, no upload — practice, not therapy.
Channel Apps — any channel, as an app
The auto-updating Double Down News app is a product, not a one-off. The same engine turns any Telegram or YouTube channel into an installable app: new uploads push to your phone, no ads, no tracking. Neutral delivery — the channel owns its audience.
Live example free. The Double Down News app runs on this engine now.
Hard Conversations — scripts that work
The five hardest talks — driving, money, moving, health, getting help — with when to raise each, word-for-word openings, what never to say, and a printable one-pager. Built from caregiver and elder-care guidance. On-device, nothing uploaded.
Free. Printable one-pagers, on-device, no account.
True or False? — the fact-checked page
Every viral "shocking fact" gets a real verdict — true, false, or mostly-true — with a one-line reason and the source. Fact-checks first, then makes it fun with a daily quiz and streak. On-device, nothing uploaded.
More fact-checked than anything. The verdict and the source are the product.
Concierge — Charon, The Golden Keys
A private concierge that quietly arranges travel, stays, transfers, experiences and the finer doors — recommended, never advertised. Knock, and Charon holds the keys.
By invitation. Recommended, never advertised — the door is yours.

Three rules every tool follows
On your device
Your files, your data, your business. Tools run locally by design — not because we couldn't build a server.
Honest about the paywall
The free tier is genuinely useful. The paid unlock adds the deep work — and it's a one-time £9.99, never a subscription.
Still here in ten years
No VC-burn runway, no "we pivoted". Boring tools built to keep working, hosted where nobody can take them away.
