Your broker credentials never touch our servers. Your data is encrypted, US-hosted, read-only, and never sold.
Linking an investment account toa third-party app is a reasonable thing to be cautious about. Here's what we've built so you don't have to be.
For the large majority of majorbrokers, your login happens directly on the broker's own site through OAuth —the same protocol used by Google, Apple, and the rest of modern webinfrastructure. Your username and password are never seen by Plaid, SnapTrade,or Ziggma. A secure token grants Ziggma permission to read your portfolio data,nothing more, and you can revoke it at any time.
Ziggma can see your positions,balances, and transactions. We cannot move money, place trades, or changeanything in your brokerage account. Data flows one way: from your broker intoZiggma. Nothing flows back.
All data is encrypted at restwith AES-256 — the same algorithm used to protect classified government data —and in transit with TLS, the standard that secures online banking. Our infrastructure is hosted on Amazon Web Services in the United States.
Behind the scenes, the connection between your broker and Ziggma is handled by one of two specialist financial data aggregators: Plaid or SnapTrade. They're the same firms that power household-name fintech apps used by tens of millions of people, and they'repurpose-built for one job — making this kind of connection safely.
Roughly 1 in 2 US adults haslinked a financial account through Plaid, which connects to more than 12,000 financial institutions across the US, Canada, UK, and Europe and powersover 7,000 financial apps. SnapTrade specializes specifically inbrokerage and retirement accounts, with access to 30+ brokers and over 125million reachable accounts.
When you click "Link account" in Ziggma:
For the small number ofinstitutions that don't yet support OAuth, credentials are passed directly to the broker through the aggregator's encrypted channel and are never seen by Ziggma. In SnapTrade's case, any stored credentials are encrypted with AWS KeyManagement Service (KMS).
Your data is protected at every layer of the stack — on Ziggma's servers, on the aggregators' servers, and in transit between them and you.
Databases and backups sit on US-based Amazon Web Services infrastructure and are encrypted with AES-256.Even if a backup were somehow obtained, it would be computationally infeasible to read without the decryption keys, which are managed separately.
Every page on Ziggma is served over HTTPS using TLS, so data cannot be intercepted between our servers and your browser. The same standard protects data moving between your broker and the aggregators.
All Ziggma data is stored on AWS infrastructure in the United States. AWS data centers are independently certified to SOC 1, SOC 2, SOC 3, ISO 27001, PCI DSS, and FedRAMP, with multiple layers of physical and network security.
We rely on Plaid and SnapTrade for the broker connection itself, and both hold the certifications that matter for financial data:
