Grímnir: Secure, Self-Hosted Password Manager for Individuals

A local-first desktop password manager, secure notes vault, and authentication app built for people who value ownership, privacy, and control.

Grímnir is designed around a simple idea:

You own it. You control it.

No subscriptions.
No SaaS lock-in.
No dependence on third-party cloud platforms.

Your passwords, notes, and authentication codes remain under your control, stored locally, encrypted securely, and accessible on your terms.

You already have the compute power.
Grímnir gives you the tools.

Built for Independence

Most modern software asks users to surrender control in exchange for convenience.

Grímnir takes a different path.

Run it locally on your own computer, or host it yourself if you choose. Your data is not mined, analyzed, or locked behind a subscription model. There are no recurring fees, forced upgrades, or cloud dependencies.

You buy the software once. You keep using it.

This is software designed to work for you, not software designed to extract value from you.

Security Without Compromise

Grímnir protects sensitive information using trusted encryption standards including PBKDF2 and AES.

Passwords, private notes, recovery keys, authentication codes, and sensitive information are stored securely with strong local encryption.

No third-party access.
No external dependency.
No hidden infrastructure.

Only you control your vault.

Built for Individuals

Grímnir is built for individuals, creators, developers, independent thinkers, and privacy-conscious users.

It is not designed around enterprise surveillance culture, growth metrics, or platform dependency.

It is built for people who value:

• Ownership
• Local-first software
• Offline functionality
• No subscriptions
• No lock-in
• Privacy as default

Sustainable Independent Software

Grímnir is created by Social Climate Tech, a non-profit organization focused on independent and sustainable technology.

Instead of subscriptions, tracking, advertising, or investor-driven growth models, Grímnir is supported through a small one-time contribution that helps fund continued development and long-term maintenance.

Every contribution helps support ethical, privacy-respecting software focused on social good, sustainability, and digital independence.

We believe software should:

• Respect people
• Remain accessible
• Avoid artificial upgrade cycles
• Reduce dependence on centralized systems
• Empower users instead of platforms

Why Grímnir?

Because your digital life should not depend on:

• Subscriptions
• Cloud lock-in
• Tracking
• Advertising models
• External control

You already own the hardware.
You already have the compute power.

Grímnir gives you the tools to take control back.

Own it. Control it.
