Your app forgets everything.
One prompt fixes it.
You built something amazing with AI. But when someone adds a product, logs a workout or reaches a new level, it disappears. Copy one prompt into your AI tool and your app remembers everything, for everyone, on every device.
Sound familiar?
You refresh and it's all gone
Your to-do list, expenses or game progress vanish the moment the page reloads.
Changing anything means rebuilding
Every new price, menu item or opening time means asking your AI to rebuild and republish the whole site.
It only works on your laptop
You see your data, but your friends, visitors or your own phone see an empty app.
"Just set up a database"
Your AI asks for servers, keys and settings you've never heard of. You only wanted it to work.
Every lost entry is something you'll never get back
Lost visitors
When a game forgets their high score or a quiz forgets their answers, people leave and don't come back.
Lost hours
Days spent fighting databases and tutorials instead of building your idea.
Lost momentum
Projects stall at "it works, but nothing saves", and great ideas never launch.
The fix
Give your app a memory. It's just a prompt away.
dontlosedata is a safe place on the internet where your app keeps its information. You don't install anything or learn anything. Your AI tool does the work.
Copy your prompt
Press one button below. Your prompt already includes your own private storage.
Paste it into your AI
In Lovable, Replit, ChatGPT, Claude or any AI builder. Then say what you want, like "save my to-do list".
That's it
Your app now keeps every task, score and setting. Safely, permanently, on every device.
Your prompt is ready
We made it just for you. It already includes your own private storage, so there's nothing to set up.
We add this to your prompt so your AI knows exactly what to keep.
- 1 Copy the prompt
- 2 Paste it into your AI tool
- 3 Your app remembers everything

You don't need to understand it. Your AI tool does.

Always in your hands
Need to change something later? Just change it.
Your AI sets everything up, but you're never stuck waiting for it. Open your dashboard and change anything your app has saved: a price, a menu item, tomorrow's opening hours, a typo in an announcement. It's as easy as filling in a form, and visitors see the change the next time they open your app. No AI, no rebuild, no republish.
-
Edit it like a form
Everything is a simple row with a name and a value. Type to change it, tap a switch for yes or no.
-
Add, remove, reorder
Add a new item in one tap, remove the old one, or move things up and down. Your lists keep their shape.
-
Find anything in seconds
Search everything your app saved and jump straight to it, even in long lists.
-
Mistakes can't sneak in
Every change is checked before it's saved, and we point you to anything that needs fixing. Changed your mind? Press Undo.
Works just as well on your phone, so you can fix things on the go.
What you get
Nothing gets lost
Everything your app saves stays saved, even when visitors close the page.
Works everywhere

Change it yourself, anytime
Your dashboard shows everything your app saved. Fix, add or remove anything as easily as filling in a form, even from your phone.
Update your site without code
Add a product or change a price with a simple form. No rebuild, no republish. Spam bots are caught automatically.
Private when you need it
Add a lock so only your app can read or change your information.

Works with the tools you already use
If your AI tool can build a website or app, it can use your prompt.

Questions
Do I need to know how to code? +
No. You copy a prompt and paste it into your AI tool. The AI does the technical part for you.
Which tools does it work with? +
Lovable, Replit, ChatGPT, Claude, v0, Bolt, Cursor and basically any AI tool that builds websites or apps. Plain website forms work too.
Where is my information kept? +
On our servers, in your own private storage space. Only people who have your app's link can use it, and you can add a lock to make it fully private.
Can I see and change what's saved? +
Yes. Sign in with Google and your dashboard shows everything. Change, add or remove anything yourself, as easily as filling in a form. No AI or code needed, and every change is checked before it's saved.
Do I have to sign up? +
Not to try it. The prompt works right away. Sign in (free, with Google) to keep it forever and create more.
What if my app gets popular? +
The free plan handles thousands of visitors a day. If you ever reach a limit, nothing is deleted. You'll get a clear message, and bigger plans are coming.
What isn't it for? What shouldn't I store? +
dontlosedata is made for small and medium apps, sites and side projects. If your idea looks like one of these, you'll be happier with a full database or a specialist service.
Millions of records
Huge catalogues, years of sensor readings or every click on a busy site. It's built for hundreds or thousands of items, not millions.
Fast search & reports
Searching, sorting or adding up tens of thousands of items in a split second, like a big online shop, a job board or a sales dashboard.
Personal details
Names, email addresses, phone numbers, home addresses, birthdays or anything that identifies a person.
Sensitive information
Health or medical notes, ID or passport numbers, legal documents, or anything covered by privacy laws.
Passwords & sign-ins
User accounts and logins. Use your AI tool's built-in sign-in or a service like Google sign-in instead.
Payments & money
Card numbers, bank details, wallet balances or anything that moves real money. Use Stripe or PayPal for that.
Live chat & real-time play
Chat rooms, live multiplayer games or many people editing the same thing at the same second.
Photos, videos & files
It keeps text and numbers, not images, videos, PDFs or other uploads.
Critical business records
Orders, invoices, stock counts or bookings your business can't run without, or must keep by law.
Not sure? If your app saves lists, scores, products, settings or site content, and you'd describe it as "small", it's a great fit.
Your app is one prompt away from remembering everything.
Free, no credit card, no code. It takes less than a minute.
Developer? It's a CORS-enabled JSON REST API with paths, wildcards, filters, HTML form posts and API keys.
