MemberDex — Member Directory

Tatzel Labs LLC

About this app

MemberDex is the branded member directory your community will actually use.

A self-contained mobile rolodex — completely separate from your phone's address book, with no merging or syncing into your personal contacts. Members tap a name and dial, message, email, visit a website, or get directions. Photos, custom fields, and your community's branding are all in one place.

DESIGNED FOR REAL COMMUNITIES
• Homeowners and condo associations
• Country clubs, golf clubs, and social clubs
• Service clubs and networking groups — Rotary, BNI, and chapter organizations
• Faith communities, churches, synagogues, and ministry groups
• Chambers of commerce and trade associations
• Professional and alumni networks
• School and parent-teacher groups
• Healthcare networks and provider directories
• Nonprofits and volunteer groups

WHAT MEMBERS GET
• A polished Android app branded for your community — your logo, your colors, your community page
• A searchable, sortable, category-filterable member roster
• One-tap call, text, email, website, and navigate-to-address actions
• A "My Profile" tab where each member edits their own card and photo
• Fast, secure sign-in with fingerprint or face unlock — skip retyping your password
• Private notes, on-device only
• Works offline once your directory has been synced

WHAT ADMINS GET
• A web admin dashboard for branding, members, and content
• Custom fields with type validation
• Bulk CSV import with preview-before-apply
• Bulk invitations with per-community rate limits
• Soft deactivate, restore, and a complete activity audit log
• Community backup and restore
• CSV export of your members anytime

PRIVACY AND SECURITY, PLAIN-LANGUAGE
• No advertising, no analytics, no tracking SDKs
• No access to your phone's contacts permission
• HTTPS in transit, modern TLS only, certificate pinning on the client
• Optional TOTP multi-factor authentication for admins
• Tenant-isolated database — every query is scoped to your community
• Full activity audit log with super-admin impersonation events flagged

GETTING STARTED
A community admin signs up at memberdex.app, configures branding and custom fields, and sends invites. Members receive an email with a secure invite link, set a password, and join.

MemberDex is a member directory and roster app for associations, chambers of commerce, HOAs and condo associations, churches, synagogues and congregations, service clubs like Rotary and BNI, alumni networks, country and golf clubs, and any community that has outgrown a spreadsheet or a group chat. One fast, private, native member directory — not a web page in a wrapper, and never mixed into your phone's contacts.
