Own your data.
Share it your way.

What is SMDB?

Your personal data graph

Every piece of your information starts hidden. You then decide who can see it—public, private, or shared with specific circles of trusted people.

  • 🔒 Private by default. No field is public unless you explicitly choose it.
  • One-way sharing. You share your data with someone without granting them reciprocal access.
  • 🚫 No feeds, likes, or comments. SMDB is a data-sharing tool, not a social network.
  • 🤝 Trust-based growth. New users arrive via invitations and must have SMDB accounts.

How it works

Control who sees what in 3 steps

1

Create your profile

Create a single profile tied to a unique username. Everything starts hidden—only you can decide what to reveal.

2

Define your circles

Create circles of trusted people—friends, family, colleagues. Every circle member must have an SMDB account.

Share on your terms

Toggle visibility for each field: public, private, or shared only with a specific circle. Change permissions anytime.

Use cases

Where SMDB fits in your life

Use SMDB when you want control, not exposure: networking, family coordination, professional collaboration, and sensitive information sharing—without a social-media feed.

💼

Professional networking

Share your resume, portfolio, and contact details selectively with recruiters or hiring teams.

🏡

Family coordination

Share medical info, addresses, and emergency contacts with family members only.

📋

Community organizers

Share event-related roles and permissions with trusted volunteers, without exposing everyone publicly.

💻

Open-source & software

Share your GitHub profile or CV with specific collaborators, keeping the rest private.

Privacy principles

Built for privacy, not for virality

🔒

Private by default

Every field you add is hidden until you explicitly make it public or share it with a circle.

Explicit permission only

Circle members must have SMDB accounts; you cannot share with random, unverified profiles.

One-way sharing

You choose what you disclose without granting reciprocal access rights.

🚫

No feeds or engagement

No content algorithms, no engagement metrics, no public comment sections.

📧

Invite-only growth

New users join via invitation emails, encouraging small, trusted networks rather than public discovery.

Comparison

SMDB is not a social network

Social networks are built for discovery and engagement. SMDB is built for controlled, permissioned sharing.

Default visibility Everything private Many fields public by default
Sharing model One-way, per field Mutual "friendship" or follower model
Interaction layer No feeds, likes, or comments Feeds, likes, comments, stories
Network growth Invite-only, trust-based Public discovery, mass following

Your profile, your rules

Your public profile lives at smdb.link/username. Visitors only see what you've chosen to make public—no hidden data leaks, no surprises. No followers count, no engagement stats. Just the information you decided to share.

FAQ

Common questions

How is SMDB different from a social network?

SMDB focuses on permissioned data sharing, not feeds or engagement. Nothing is public by default—you have full control over every field on your profile.

Do both people need an SMDB account to share?

Yes. All circle members must have SMDB accounts; you cannot share with unverified or anonymous users. This ensures every connection is deliberate and trusted.

Can others see what I share with every circle?

No. Each circle sees only the data you explicitly share with them. Visibility is per-field, per-circle—nothing bleeds between circles.

Is registration free?

Yes. You can create a profile and start using SMDB at no cost.

How do people join my network?

You invite them via email. They register on SMDB, then you can add them to circles and start sharing fields with them.
