Ninaivu – Your private life-memory vault

The problem

Life is full of details you only need at the worst moment.

Missed renewals

Car insurance, passport, electricity bill. A forgotten date costs money and stress.

Health details on the spot

The doctor or insurer asks for your last BP or sugar reading, and you can't recall it.

Scattered and unsafe

Notes apps, WhatsApp chats and photos are hard to search and not built to protect personal data.

Features

One calm place for everything you keep forgetting.

Organised by category, searchable in plain words, and always ready when someone asks.

IDs and policies

Aadhaar, PAN, passport, insurance and policy numbers, found in a second.

Health

BP, sugar, allergies, medicines and doctor details, ready for any appointment.

Bills and renewals

Due dates on a clear timeline, with overdue items highlighted.

Family profiles

A profile for each family member, with their own documents, reminders and blood group.

Documents

Notes and photos of where each important document is kept.

Passwords

Encrypted passwords, hidden by default, with one-tap copy and a strong password generator.

Expiry alerts

In the Windows app, notifications arrive in the background from the tray. In the browser, alerts appear while the Ninaivu tab is open.

Ask in plain words

Type "when is car insurance due?" and get the answer, not a list of files.

Encrypted backup

Download a dated, encrypted backup in one click, with a gentle reminder every 30 days.

How it works

Up and running in a minute.

Create your vault

Choose a master passphrase. Only you know it, and it never leaves your device.

Save what you forget

Add IDs, policies, passwords, readings and bills for each family member, with optional due dates.

Just ask

Ask "what's my policy number?" and see what is due soon on your dashboard.

Our privacy promise

Your memories stay yours. Always.

Ninaivu is built so that nobody else, including us, can read what you store.

Encrypted on your device

Everything is locked with AES-256-GCM encryption, using a key derived from your passphrase.

Stays on your device

Your vault lives encrypted on your device. No Ninaivu servers, no ads, no tracking. Optional sync goes only to your own Google Drive app folder, already encrypted.

Only you hold the key

We never see your passphrase or your data, so nobody can read it except you.

Your backup, your control

Export an encrypted backup file and keep it wherever you choose.

Security

How your data is protected

Plain facts, no jargon. You can check the code yourself, because every file is readable.

Strong encryption

Your vault is encrypted with AES-256-GCM. Your passphrase is stretched with PBKDF2 (310,000 rounds of SHA-256) before it is used, which makes guessing very slow.

Recovery key and Emergency Kit

When you create your vault, Ninaivu makes a random recovery key and gives you a printable Emergency Kit. If you forget your passphrase, the key unlocks your vault. Nobody else has a copy.

Offline by default, online only with your consent

Ninaivu works without the internet and has no Ninaivu accounts, servers, analytics or tracking. It only goes online if you turn on optional sync (encrypted, to your own Google Drive app folder) or use optional Ask Gemini, which sends a document to Google Gemini only after you approve it.

Locks itself

The vault locks after 5 minutes without use, and in the Windows app when you minimise it or switch away for a minute. Sensitive numbers stay hidden until you tap to show them.

Download for Windows

Ninaivu for Windows 10 and 11 (64-bit), with background reminders from the system tray. Installer size about 78 MB. Uninstalling keeps your vault, so a reinstall does not lose anything.

Vanakkam! I'm Raja. Like many of you, I've watched my family hunt for a policy number, an Aadhaar copy or a renewal date at exactly the wrong moment. I built Ninaivu so every family can keep their documents, policies, renewals, IDs and notes in one private place, synced between phone and laptop with no complicated setup. Your data stays yours, encrypted and never shared without your consent. And I wanted it priced so every family can afford it: ₹99 a year, or ₹299 once for life. Simple, honest and private. That's my promise to you.

FAQ

Frequently asked questions

No. Your data is encrypted on your device with your passphrase. We run no servers and never receive it. If you turn on sync, only encrypted data goes to your own Google Drive; Ask Gemini sends a document only when you approve it.

Use the recovery key from your printed Emergency Kit. It unlocks your vault, and then you choose a new passphrase. Without the passphrase or the recovery key, nobody can open the vault, including us.

Yes, if you wish. Passwords are encrypted with AES-256-GCM like everything else, hidden by default, and can be copied with one tap. The clipboard is cleared after 30 seconds. A strong password generator is built in.

No. Ninaivu works fully offline. The internet is used only if you choose optional Google Drive sync or Ask Gemini.

Ninaivu alerts you about anything overdue or due soon: 7 days before by default, or the number of days you choose for each item. In the Windows app, it runs quietly in the system tray and sends Windows notifications every 30 minutes, even when the window is closed. In the browser, alerts only appear while the Ninaivu tab is open.

Turn on Google Drive sync with the same Google account on the new device, or export an encrypted backup, copy the file across and import it with the same passphrase.
