How Summarum Works

The idea

Summarum is a manual, privacy-first tracker for numbers over time.

It does not connect to banks. It does not download transactions. It does not run in the background.

Instead, you stay in control.

Step 1: Create a series

A series is simply something you want to track over time.

Examples:

• Checking account balance
• Stock portfolio value
• Crypto wallet total
• Car or motorbike mileage
• Body weight

You can create as many series as you want.

Step 2: Add values (two ways)

Option A: Manual entry

Type a value and a date. Done.

Option B: Screenshot or photo

This is where Summarum shines.

1. Open the app that shows your number (banking app, broker, scale, odometer).
2. Take a screenshot or photo.
3. Share it to Summarum.

Summarum analyzes the image on your device:

• extracts the number
• detects the date
• suggests the right series

You can always adjust before saving.

Step 3: See trends, not noise

Summarum turns your values into simple graphs:

• one series at a time
• or multiple series together

This lets you see:

• long-term trends
• progress over months or years
• how different values evolve side by side

No spreadsheets. No logins.

What Summarum is (and isn't)

If you're looking for automation, Summarum is probably not for you. If you want clarity and control, it probably is.
