FAQ · Trust and evidence

Does my strategy code or data ever leave my machine?

No. Reamer Research and Reamer Server run entirely on your own machine, and neither sends strategy code, data, results or orders to Reamer Labs. Their only contact with Reamer Labs is activating or deactivating a licence, which sends the licence key and a one-way hash of the machine's identity. There is no telemetry, no usage analytics and no crash reporting.

What is sent, and when

  • On activation: the licence key and a machine fingerprint, which is a SHA-256 hash of the machine's hostname and network hardware address. The licence server checks the key, binds it to that machine, and returns a signed licence.
  • On deactivation: the same, to release the seat so you can move it to another machine.
  • At any other time: nothing. Each later start checks the signed licence on your machine, with no network call, and a running process does not check in.

What is never sent

  • Strategy code, parameters or configuration
  • Market data or any other input data
  • Backtest results, orders, fills or positions
  • Usage statistics, feature analytics or crash reports

Reamer Server's orders go to your broker through a connector you write, not through Reamer Labs.

Checking it yourself

After activation, both products run with no internet access, so you can block outbound traffic and confirm they work. The Reamer Server deployment guide says that any traffic from a running process to the licence server is unexpected and should be reported. The kit also includes a vendor questionnaire pack with a data-handling statement for your firm's review.

What Reamer Labs does hold

Your email address, the licensee's name, the licence key, the machine fingerprint and activation times. Payment details stay with Paddle, which handles checkout. See the privacy policy.

Next questions

Is it secure? Can it pass my firm's vendor review?Each kit ships the documents a vendor review usually asks for, including a filled-in security questionnaire, a software bill of materials and signed release files. The security testing behind them was done by Reamer Labs itself; no outside firm has audited either product. Whether that is enough depends on your firm's policy, and you can test the binaries yourself.Reamer Labs is one person. What happens if it stops?Your installed copy keeps running until its licence term ends, because the licence is checked on your machine, not against a server. What stops is updates, support, renewals and moving the licence to a new machine. If you need protection beyond that, you can set up a source escrow at your own cost, which releases the source to you only if Reamer Labs becomes insolvent or ends the product.Are there customer reviews?Not yet. Reamer Research and Reamer Server are newly launched, and there are no published customer reviews or testimonials. Reviews will appear on the public software listings as customers post them. Until then, the evidence you can check is the uncut integration recordings, the published benchmark method and raw data, and the trial.Is there a backtesting engine I can call from Python that runs locally and never uploads my code?Yes. Look for an engine delivered as a library you run on your own machine, with a licence that is checked offline, and confirm it by running it with the network cut off. Reamer Research is one: a compiled engine with a pure-Python binding that ships in source, which runs offline after a one-time activation and sends no strategy code, data or results to Reamer Labs.
