Tools that actually work. On your device, no uploads ever.
Ten boring on-device tools that actually work: read your Facebook export, find your passive income stream, cook what's in your kitchen. Paid features unlock deeper analysis once, never subscribe. No tracking.
On-device tools that actually work
Every tool runs in your browser, is free to try, and honest about what it costs.
Data Forensics Tool — read your own Facebook export
Meta hands you your file — every message, photo, location, ad profile. Data Forensics Tool opens that export on your own device and shows you what's in it. No upload, no account. The scan is free — your people, your timeline, full-text search. What the file says about your life is the Deep Dive. You'll know it when you see it.
Free — the core
- Open your export on-device
- People, timeline, full-text search
- Nothing ever uploaded
✦ The Deep Dive — one lifetime unlock
- What your export says about your relationships — every decade of them
- The advertisers who built your profile, by name
- Where your data says you've been — and what else it keeps
- Keepsakes you can hold — 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.
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.
Caregiver Cost Calculator — what caring actually costs
Most families cannot answer this, which is why the argument about money never settles. Enter the hours you give and what you pay out, and it works out the real figure — plus what replacing that care would cost, and the specific things to do about it. Free, ungated, on your device.
Free. No account needed to use it. Name and email only unlock printing.
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.
Questions people actually ask
Straight answers, no marketing spin.
How do I read my Facebook data export?
Download your data export from Facebook (Settings > Your Facebook Information > Download Your Information), then open the file in the Data Forensics Tool. It runs entirely in your browser — no upload required.
Is DataVault AI free?
Yes — every tool's core is free with no account and no subscription. The Data Forensics Tool's deep features (Deep Dive, relationship maps, Memory Book) are a one-time £9.99 lifetime unlock, never a subscription.
Does DataVault upload my Facebook data?
No. DataVault AI runs entirely in your browser — your export never leaves your device. Only the optional £9.99 payment touches Stripe, and your access key is emailed to you at checkout.
Who is behind DataVault AI?
DataVault AI builds boring, dependable tools that keep your data yours. Reach us at timolify+datavaultai@gmail.com.
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.
