Frequently Asked Questions
A practical overview of how CTRON Loop handles your AI keys, your knowledge, billing, privacy, and AI-generated outputs.
Last updated: June 28, 2026
What does CTRON Loop actually do?
CTRON Loop helps freelancers, founders and small teams get everyday work done with AI. You upload your own files, bring your own AI key (or use managed AI), run tasks from one simple box, and save repeatable work as loops — every output grounded in your own knowledge.
What does BYOK mean here?
BYOK means bring your own key. CTRON Loop uses your connected OpenAI, Anthropic, or Perplexity key for task execution, so AI usage is billed by your provider account rather than by CTRON Loop.
Why not just use ChatGPT or Claude directly?
CTRON Loop runs on those models (bring your own key), so it isn't either/or — it's how you use them for the work you repeat. Instead of re-pasting your context every time, you upload your documents and spreadsheets once and every task is grounded in them; you save tasks you repeat as one-click loops; and for spreadsheets the numbers are computed by a deterministic engine (the AI only designs the layout) rather than guessed. For one-off questions or brainstorming a plain chatbot is fine — CTRON Loop earns its place when you do the same work repeatedly and need it grounded in your own knowledge.
What if I don't have an AI key?
You can turn on CTRON AI in Settings → Providers and run tasks without connecting your own key. It runs on open models through our inference provider, so your prompts are processed by that provider. CTRON AI is included with each plan up to a monthly limit and is not free or unlimited — it costs us per use, so it is metered. Bringing your own key remains the default and lets you run on your own provider account.
Which files can I upload?
The current product supports PDF, DOCX, TXT, CSV, and XLSX uploads. Documents are processed into company context, while spreadsheet uploads are profiled for safe task grounding without sending raw rows indiscriminately to AI.
Who can access my workspace data?
The product is designed around workspace isolation with row-level security and workspace-scoped storage paths. One user's workspace should not be able to access another user's data through the app.
Do you use my content to train shared models?
CTRON Loop does not describe the product as a shared model-training service. Your task requests are processed through the provider you connect under that provider's own policies, and your workspace data is stored so the app can operate for your account.
How do subscriptions and cancellation work?
Paid plans renew monthly. You can manage or cancel through the Stripe billing portal linked from the in-app billing page. Cancellation normally stops the next renewal and keeps access through the current paid period.
What currency and taxes apply?
Prices are set in GBP (with an approximate USD figure shown for reference). Where supported, checkout presents and charges in your local currency, and any VAT, GST, or US sales tax is calculated and added at checkout based on your location. You can add a business tax ID at checkout, and invoices show the tax applied.
Do you offer refunds?
Charges are generally non-refundable once a billing period has started, except where required by law or where there has been a duplicate or clearly incorrect charge. The detailed rule is on the Refund Policy page.
Is CTRON Loop legal, tax, or financial advice?
No. CTRON Loop generates AI-assisted business outputs that must be reviewed by a human before reliance, especially for legal, financial, employment, or regulated decisions.
