## How tracking works

Growth is noisy day to day: log your follower count with the date, ideally once a week. The tracker sorts entries by date, computes the change between the first and last entry, and annualizes it into per-week and per-30-day rates. The 90-day projection extends your current weekly rate; it is a straight-line guess, not a promise.

## Reading the chart

Bars show your follower count at each logged date, scaled to your range. A steady upward slope is healthy growth. Flat stretches mean your content is holding the audience but not reaching new people; drops usually follow a controversial post, a purge of inactive followers, or Instagram removing bots.

## What good growth looks like

For small accounts, 2% to 5% per month is solid; for accounts over 100k, 0.5% to 1% per month is normal because the base is large. Compare your rate to your own history, not to viral accounts. A rising rate after a content change tells you the change worked.

## Your data stays on your device

Entries are stored in your browser's local storage under a Toolantern key. Clearing site data deletes them. Nothing is uploaded, there is no account, and nothing leaves your device.

## Frequently asked questions
### How many entries do I need?

At least two entries with different dates. Weekly logging gives the most useful chart; two entries a month apart is the minimum for a meaningful rate.

### How is the 90-day projection calculated?

Your current weekly growth rate extended 90 days in a straight line. It assumes nothing changes: no viral posts, no algorithm shifts. Treat it as a baseline, not a forecast.

### Where is my data stored?

They stay in your browser's local storage. They are never uploaded or sent anywhere. Clearing your browser's site data deletes them.

### Can I fix a wrong entry?

Add an entry with the corrected count and date. The tracker sorts by date, so it slots in correctly. Delete and re-add if you entered the wrong date.

### What is a good monthly growth rate?

Small accounts: 2% to 5% per month is solid. Over 100k followers: 0.5% to 1% per month is normal. Compare against your own history first.

### My growth is flat. What should I do?

Flat growth usually means your content reaches your current audience but not new people: try reels, collaborations, or trending formats. Drops often follow purges or controversial posts.

### How do I add an entry?

Pick a date and enter your follower count. Log weekly for best results.

### Is my data sent anywhere?

No. The tracker runs entirely in your browser. You can disconnect from the internet after the page loads and it still works.
