Tool Safety Index

A great tool and a safe tool are two different questions.

The market can tell you which accounting software is best. It cannot tell you what a vendor's binding terms let them do with your client data. So we read the actual terms of service, privacy policy, and DPA for every tool here, and summarize where each vendor's terms land for client data. Supported — the terms support it on the normal business tier. Conditional — supported once you get one specific setting or tier right. Not supported — a binding clause means the terms don't support client data. Undisclosed — the public terms don't say yet. It's our read of the published terms, not a recommendation about the product — every entry is dated and cited to primary source. Behind each one sits a scorecard of five independent checks — no-training, DPA, certifications, US residency, retention — with no composite score: each check stands alone so you can challenge any single cell. A separate connectivity note tracks which tools expose an API or MCP. Open any tool to see its alternatives in the same category, or add two to four tools to the compare tray for a side-by-side scorecard.

Help us keep this right. Every status here is a best-effort read of each vendor's terms as of the date on the card — with 228 tools, we don't guarantee we caught everything, and vendors change terms without notice. If you use a tool and something looks wrong or outdated, open it and hit Flag for review with what you saw. Every flag is tracked and re-verified against primary source, and the entry is corrected or the flag answered. That loop is the point.

By task: what §7216 says

The Index above answers “can client data go in this tool?” This answers the other half: whether the task itself needs written consent, grounded in the regulation.

Task verdicts apply IRC §7216 to the task and are grounded in primary law, unlike the tool statuses above, which are read from vendor terms. The footer disclaimer below covers both.
