Privacy First​

Usernames or avatars are never disclosed. Even admins cannot access other users’ history or records - ensuring full privacy for all members .

BMI record actions are protected with permission and ownership checks, so members can only manage their own BMI data.

Admin Options​

Title → Sets the title displayed on the BMI Calculator index page.
Description → Add a short intro or HTML description at the top.
Meta description → SEO-friendly description for the calculator page (150–160 chars).
BMI history per page → Set how many records show per page (default 20).
(Defaults are pre-populated for easy setup.)

User Group Permissions​

Control exactly who can access and manage BMI data on your forum. Permissions are fully flexible and handled per user group:

• Can use BMI Calculator → Control which users can access the calculator at all.
• Can edit own BMI record → Allow users to update their previously saved BMI entries.
• Can delete own BMI record → Allow users to remove their own BMI entries.

This ensures privacy and control, letting members manage their own data while preventing others (including admins) from editing or deleting someone else’s records.

Why Add This To Your Forum?​

• Boost Engagement → Members will return to track progress.
• Faster Repeat Tracking → Latest values are pre-filled so members can quickly log a new update.
• Wider Audience Support → Metric and US units make the tool comfortable for international communities.
• Encourage Interaction → Sparks discussions around health, lifestyle, or fitness goals.

• Value Beyond Threads → Adds a utility your members can use anytime.
