Performance

YAPL is running slowly. What can I do?

Try these steps:

1. Clear browser cache

   • Chrome: Settings > Privacy > Clear browsing data
   • Firefox: Settings > Privacy > Clear Data

2. Close other tabs

   • Too many open tabs use memory

3. Disable browser extensions

   • Some extensions can slow down pages

4. Check your internet connection

   • Slow connection affects load times

5. Try a different browser

   • Rule out browser-specific issues

6. Update your browser

   • Older versions may have performance issues

Why do large plans load slowly?

Plans with many tasks (hundreds) require more processing. Tips:

• Use filters to show fewer tasks at once
• Collapse task hierarchies
• Consider splitting into multiple plans

How much data can YAPL handle?

Tier limits help maintain performance:

These limits ensure smooth operation for all users.

Data & Security

Is my data secure?

Yes. YAPL implements multiple security measures:

• HTTPS encryption for all data transfer
• Row-level security (RLS) for data isolation
• Secure authentication via Supabase
• No storage of full payment card numbers

Where is my data stored?

YAPL uses Supabase for data storage, which runs on enterprise-grade cloud infrastructure with:

• Regular backups
• Geographic redundancy
• Compliance certifications

Who can see my data?

• Your workspace data: Only workspace members with appropriate access
• Cross-workspace: Workspaces are completely isolated
• YAPL staff: Limited access for support purposes only

Is my data backed up?

Yes. The database is backed up regularly. For critical data, we recommend also maintaining your own exports.

Can I export my data?

Professional tier users can export data in various formats. Look for export options in the actions menu of relevant features.

Authentication

How does login work?

YAPL uses Supabase Auth for secure authentication:

• Email and password authentication
• Secure session management
• Password reset via email

Why was I logged out?

Automatic logout occurs:

• After extended inactivity
• When sessions expire
• After password changes
• When clearing browser data

Simply log in again to continue.

Can I stay logged in?

Sessions persist for a reasonable duration. If you're being logged out frequently:

• Check that cookies are enabled
• Don't clear browser data for YAPL
• Check browser extensions that might affect cookies
