Comparison
Best free portfolio trackers for privacy
Most free stock portfolio trackers earn their keep by aggregating your financial life — link a brokerage, link a bank, accept the data economy that follows. For privacy-conscious investors, that trade is the whole problem. This is a plain comparison of how the common approaches handle your data, and where a local-first tracker fits.
Three ways people track a portfolio
Local-first tracker
Holdings live on your device. No broker login, no required account. MomentumTrackr is built this way.
Account aggregators
Auto-sync by linking brokerages and banks. Convenient, but your positions sit in someone else's cloud.
Spreadsheets
Total control, total manual effort. Private, but no momentum or concentration signal layer.
Side-by-side comparison
| What matters | MomentumTrackr | Aggregators | Spreadsheet |
|---|---|---|---|
| No broker login required | Yes | No | Yes |
| Works without an account | Yes | No | Yes |
| Data stays on your device | Local-first | Cloud | Your file |
| Momentum & regime signals | Yes | Partial | No |
| Concentration awareness | Yes | Partial | Manual |
| No ads or data resale | Yes | No | Yes |
| Cross-device sync (optional) | Opt-in | Yes | No |
| Setup time | Seconds | Minutes + linking | Hours |
Aggregator behavior varies by product; "Partial" reflects that some offer momentum or concentration views, often behind an account.
Data sovereignty
Why "no broker login" is the real differentiator
The moment a tracker holds read access to your brokerage, your portfolio becomes its asset too. MomentumTrackr takes the opposite stance: you enter positions yourself, the data lives locally by default, and the Free tier never asks who you are. If you later want your workspace on more than one device, sync is opt-in — a choice you make, not a condition of entry.
- No brokerage or bank credentials, ever.
- Free tier is anonymous and stored on your device.
- Momentum, concentration, and regime signals without surveillance.
Common questions
What is the most private free stock portfolio tracker?
One that keeps holdings on your own device and never requires a brokerage login. MomentumTrackr's Free tier is local-first and stays anonymous — no account needed.
Do I have to link my brokerage to track a portfolio?
No. Aggregators ask you to link accounts for auto-sync, but you can track manually instead. MomentumTrackr never connects to a brokerage — you stay in control of the data.
Is MomentumTrackr really free?
Yes. The Free tier is anonymous and local-first. Paid tiers add cross-device sync and AI-assisted analysis, but core tracking is free.
