Privacy

Effective November 10, 2026

Your spreadsheets stay in your browser

The prior and current pay application tables you paste or load (CSV or .xlsx), the comparison name and the results are processed in your browser and stored only in this browser (IndexedDB), together with the purchase record of an unlocked comparison. They are never uploaded to PayAppDelta. CSV, Excel and PDF files are created in your browser and downloaded directly; PayAppDelta sends no email and connects to no accounting or project system.

We cannot restore comparisons you remove from this browser or lose by clearing site data. Keep your source files and, for unlocked comparisons, the purchase record.

What the server receives (operational order data)

This is the only information that reaches our server, and it contains no rows, line IDs, amounts, filenames or document data:

• Checkout: the payment method you chose, the comparison’s random ID (a UUID that says nothing about your business) and a random checkout attempt ID. The server creates the checkout with Square or PayPal and returns a signed ticket that your browser keeps.
• Payment verification: the server keeps the provider order identifier, the comparison ID, a random per-attempt value, and payment status in a private order ledger. It checks with Square or PayPal until the provider confirms a $49 USD payment or the order closes. After a confirmed payment, the return link can restore the unlock in another browser; the server stores only a keyed hash of that return code.
• Unlock check: when you open an unlocked comparison the comparison ID and purchase record are sent so the server can confirm them.
• Campaign counters: the server counts real free CSV exports, hosted-checkout starts and provider-confirmed live sales, with a coarse campaign label from a fixed list (for example payappdelta_guide, payappdelta_launch, payappdelta_materialcredit or payappdelta_tradeclose), the language “en”, payment provider, mode and the integer price paid. It stores no IP addresses, cookies, account identifiers, row counts, amounts from your documents, file names or document data with these counts. The analytics table uses a keyed hash of the order number to avoid double-counting. Sandbox payments are not counted as sales. The public sample is never counted and never charged.

Payment providers

Payments are handled on Square’s or PayPal’s own pages under their privacy policies. PayAppDelta does not see or store card numbers or PayPal credentials.

Local storage

Besides IndexedDB the app uses local storage for the last comparison you opened and a campaign label from the link you arrived by (kept 30 days). No advertising or third-party tracking scripts are used.
