Everything you need to understand your portfolio

Most portfolio trackers give you a balance. Tendra gives you the tools to actually understand how your investments are performing and where your risks lie.

Multi-Broker Aggregation

Import PDF statements from Interactive Brokers, Fidelity, Merrill, and other major brokers. See every account in one unified dashboard.

Institutional-Grade Analytics

Go beyond basic P&L. Track time-weighted returns, Sharpe ratio, alpha and beta versus benchmarks like SPY, QQQ, and VTI, plus max drawdown and daily volatility.

Allocation Intelligence

Visualize your exposure by asset class, sector, industry, and account. Identify concentration risk and rebalancing opportunities at a glance.

Mobile-First PWA

Install Tendra on your phone or tablet like a native app. Check your portfolio anywhere with a responsive interface designed for touch.

Real-Time Market Data

Live quotes overlay your holdings so you always see current values. Track day-over-day changes and portfolio momentum in real time.

Encrypted at Rest

Every holding, transaction, and account number is encrypted with AES-256-GCM before it touches the database. No broker logins, no API keys, no plaintext financial data — ever.

Analytics that go beyond the basics

The same performance metrics used by institutional portfolio managers, calculated automatically from your brokerage statements.

Time-Weighted Return

True investment performance, independent of cash flows

Sharpe Ratio

Risk-adjusted return relative to a risk-free rate

Alpha & Beta

Performance versus SPY, QQQ, VTI benchmarks

Max Drawdown

Daily Volatility

Standard deviation of daily returns

Sector Exposure

Concentration across GICS sectors and industries

Your financial data is encrypted. Period.

We built Tendra with the security model we'd want for our own portfolios. Your data is encrypted before it ever reaches the database — not as an afterthought, but as a core design principle.

AES-256-GCM encryption at rest

Every holding quantity, price, transaction amount, and account number is encrypted with AES-256-GCM — the same standard used by banks and government agencies — before being stored. Even if the database were compromised, your financial data would be unreadable.

No broker credentials needed

Tendra never asks for your brokerage login, password, or API keys. You export a PDF statement from your broker and upload it directly. Your broker accounts remain untouched and unlinked.

Passwordless authentication

No passwords to remember, leak, or get phished. Sign in with a one-time code sent to your email. Sessions are secured with HTTP-only cookies and rate-limited to prevent brute force attacks.

Account numbers are masked

Account numbers are never displayed in full — not in the UI, not in API responses. Only the last four characters are shown, and the full number is encrypted in the database.

Three steps to your complete portfolio view

1

Upload your statements

Export a PDF statement from any supported broker and upload it to Tendra. We parse positions, transactions, and account details automatically.

2

See your unified dashboard

All your holdings appear in a single view with live market prices. Filter by account or see the aggregate across every broker.

3

Analyze performance

Track returns over time, compare against benchmarks, and drill into allocation by sector, asset class, and industry.

Built for investors who outgrew spreadsheets

If you manage investments across multiple brokers and want real analytics instead of guesswork, Tendra is for you.

Multi-Account Investors

You have accounts at 2+ brokers and are tired of logging into each one separately. Tendra gives you one place to see everything.

Performance-Conscious Investors

You want to know your actual returns — time-weighted, benchmark-adjusted — not just what your broker's summary page shows.

Risk-Aware Investors

You want to understand your concentration risk, sector exposure, and how your portfolio behaves in drawdowns before they happen.

Self-Directed Investors

You make your own decisions and want institutional-quality tools without paying for a financial advisor or Bloomberg terminal.

Frequently asked questions

What is Tendra?

Tendra is a free investment portfolio tracker that aggregates your holdings from multiple brokers — including Interactive Brokers, Fidelity, and Merrill — into a single dashboard. It provides institutional-grade analytics like time-weighted returns, Sharpe ratio, alpha/beta versus benchmarks, allocation analysis, and real-time market data.

How does Tendra import my portfolio data?

You upload PDF statements exported from your brokerage. Tendra parses the statements to extract positions, transactions, and account details. No broker login credentials or API keys are needed — your accounts remain secure.

Which brokers does Tendra support?

Tendra currently supports statement imports from Interactive Brokers, Fidelity, Merrill Lynch, and other major brokers. Support for additional brokers is added regularly.

What analytics does Tendra provide?

Tendra calculates time-weighted returns (TWR), Sharpe ratio, alpha and beta versus benchmarks (SPY, QQQ, VTI), maximum drawdown, daily volatility, and provides visual breakdowns of allocation by asset class, sector, industry, and account.

Is Tendra free?

Yes, Tendra is free to use. Sign up with just your email address — no credit card required.

Can I use Tendra on my phone?

Yes. Tendra is a progressive web app (PWA) that you can install on your iPhone, iPad, or Android device. It works like a native app with offline support and a mobile-optimized interface.

How does Tendra protect my financial data?

All sensitive data — including account numbers, holding quantities, prices, transaction amounts, and portfolio values — is encrypted with AES-256-GCM before being stored in the database. Each value is encrypted with a unique initialization vector. Account numbers are masked in the UI and API responses, showing only the last four characters. Tendra never stores or requests your brokerage login credentials.

How is Tendra different from other portfolio trackers?

Most portfolio trackers require your broker login credentials and store your financial data in plaintext. Tendra takes a fundamentally different approach: import via PDF (no broker access needed), AES-256-GCM encryption at rest for all financial data, and institutional-grade analytics including Sharpe ratio, alpha/beta, drawdown analysis, and multi-dimensional allocation views — all unified across every broker you use.

Stop guessing. Start seeing your full picture.
