Linc Documentation
Everything you need to know about Linc — what it is, how it works, and how your data is protected.

What Is Linc?
Linc is an iOS friendship tracker that helps you maintain meaningful connections with the people who matter most. Modern life makes it easy to drift away from close friends and family — not out of indifference, but because there's no system to keep you intentional about staying in touch.
Linc solves this by letting you log interactions with people you care about and set personalized reminder intervals for each one. When it's been longer than your chosen interval since your last logged interaction, Linc sends a gentle notification reminding you to reach out.
Unlike social media or messaging apps, Linc is entirely private. You decide who's in your list, when you've connected with them, and how frequently you want reminders. The app never reads your messages or social feeds. You can optionally grant contacts access to quickly add people from your address book.
How Linc Works
1. Add Your People
Start by adding the friends, family members, or colleagues you want to stay in touch with. You can add people manually or grant Linc access to your contacts to quickly pull in names and photos from your address book.
2. Set a Reminder Interval
For each person, you choose how often you want to connect — weekly, biweekly, monthly, quarterly, or a custom number of days. This interval is personal: you might check in with your best friend weekly and a former colleague quarterly.
3. Log Interactions
Whenever you connect with someone — a call, a coffee, a text exchange that felt meaningful — you log it in Linc. The app records the date and updates your interaction history. This is how Linc tracks when you last connected.
4. Receive Smart Reminders
When your chosen interval passes since the last logged interaction, Linc sends a notification. The notification is your cue to reach out — a text, a call, or planning to meet up. Once you've connected, log the interaction to reset the clock.
5. Review Your Relationship Health
Linc's home screen gives you an at-a-glance view of who needs attention. People overdue for contact appear at the top. You can see when you last connected and how long it's been, helping you prioritize who to reach out to first.
Privacy Model
Linc is built on a privacy-first architecture. All data — your friend list, interaction logs, reminder settings, and notes — is stored on your device. If you have iCloud sync enabled, data is also stored securely in your personal iCloud account for cross-device access. No data is ever sent to servers owned or operated by Linc or CoeCode.
What Linc Does NOT Do
- Send your data to Linc or CoeCode servers
- Read your messages or call history
- Connect to any social media platform
- Transmit your data to any third-party server
- Require an account or login
What Linc DOES Do
- Store data on-device (with optional iCloud sync)
- Work completely offline
- Send local push notifications only
- Keep data private — on your device and your iCloud only
- Respect your notification preferences
Linc requires no account creation. Your data is yours — if you delete the app, data is removed from your device. With iCloud sync enabled, your data persists securely in your personal iCloud account across devices. Without iCloud sync, data lives only on the device running Linc.
