Your data, your review.

Updated 20 October 2026. Operated by DUOPORE VENTURES PTE. LTD., Singapore UEN 202628284M. Written support and privacy enquiries: 68 Circular Road #02, unit no. 001, Singapore 049422.

Website

Input files and business information are processed in your browser tab. We do not upload these files, store your inputs or add analytics trackers. Downloads are generated on your device. Clear removes working inputs; downloaded files remain on your device. Close the tab to discard working state. Fictional examples are labelled.

ChatGPT tools

Data you explicitly supply to the MCP tool is processed transiently on the hosted service to generate a reviewed output. The application has no database, does not log request bodies and does not send or publish your documents. The output and downloadable file data are returned to your ChatGPT session. ChatGPT handles conversation and tool records under its own terms. Use only information you are permitted to share.

Costs and hosting

This release does not call an additional paid AI model or start a checkout. Our hosting, database and other operating expenses remain our responsibility; a customer's ChatGPT subscription does not pay them. Free output does not mean the service has no operating cost.

Hosting

ChatGPT Sites may process technical requests for security and availability. No application storage does not mean the hosting provider or ChatGPT keeps no technical records. OpenAI privacy policy.

Bounded results

One draft, one EUR, USD or GBP currency, up to 25 lines. User supplies invoice number, dates, tax treatment and rates. No sending, payment collection, bookkeeping, e-invoice standard or tax certification.

PDFs use a Latin/Greek/Cyrillic Noto Sans font. If characters are unsupported, a text file replaces the PDF and the error is shown; Excel and JSON preserve the source text.

Files are user-reviewed drafts. The tools do not certify legal, tax, accounting or source accuracy. There is no paid promotion or checkout in the ChatGPT connection.

Singapore PDPA data protection officer and contact for deletion requests and data incidents: Christoph Kaesler, at the email and business address above.

EU representative under Article 27 GDPR: Kristina Liney, Burchardstraße 4, 18233 Neubukow, Germany. Contact the EU representative by post there or email the operator marked “For the EU representative” for routing. The Singapore PDPA DPO role does not itself appoint a GDPR DPO. Privacy enquiries may also be sent to the operator's email above for routing to the appropriate contact.

Share only what the task needs

ChatGPT may choose relevant conversation or enabled-memory information for a tool call. The tool asks for task fields, not a whole conversation or personal profile. Review what you share; a field limit or privacy filter cannot detect every sensitive fact or undo a client transmission. Do not supply credentials, government IDs, card details, medical information, child profiles or unrelated third-party records. Use aliases where a real identity is unnecessary. Nothing is automatically sent to an employer, client or marketplace.

Purposes and legal bases

Where GDPR applies, an individual's requested preparation, export or optional account service uses Article 6(1)(b). Company-contact support and administration use Article 6(1)(f), with the interest of answering and managing that business request. Security and availability use Article 6(1)(f) to protect the service and its users. Applicable EU or Member State recordkeeping duties use Article 6(1)(c). We do not make automated hiring, housing, admission or other eligibility decisions.

Recipients, hosting and international processing

OpenAI provides ChatGPT Sites hosting and, when you use the connection, ChatGPT. Sites uses hosting service providers including Cloudflare; technical requests can include IP address, route, time and headers. Provider logs are distinct from application input storage. See the Sites DPA, OpenAI privacy policy and Cloudflare privacy notice.

DUOPORE operates in Singapore, which has no general EU adequacy decision. Provider processing can also occur in the United States and other countries. The Sites DPA describes safeguards, including standard contractual clauses, for processing within its scope; it does not by itself establish every DUOPORE transfer. Applicable EEA and Singapore transfer requirements must be met for the actual processing. Contact us for the safeguards relevant to your request or an available copy with unrelated confidential information removed. This service does not promise EU-only storage.

Google processes support emails sent to our Gmail contact under the applicable email terms and Google privacy policy. Do not email entire CVs, source files or unnecessary sensitive material.

Retention and privacy requests

Inputs are voluntary. A requested calculation, reply or account feature cannot complete without its necessary fields; you can stop instead. No personal fields are required merely to read this notice. Support is not a marketing signup.

The tool-specific storage and deletion behaviour is described above. Downloaded files and ChatGPT conversation history remain under your control and the relevant platform's settings. Support correspondence is kept while needed to resolve the enquiry, document its handling or meet an applicable legal obligation; it is then deleted or anonymised when no longer needed. Provider technical logs follow the provider's retention rules.

Contact ch.kae88@gmail.com or the EU representative to request access, correction, erasure, restriction, portability or objection where applicable. Consent can be withdrawn for future processing without affecting earlier lawful processing. Singapore PDPA provides applicable access, correction and consent-withdrawal rights. Legal conditions and exceptions apply. We respond without undue delay, normally within one month under GDPR, and explain any permitted extension within that month; other requests follow their applicable statutory requirements. Supply only what is necessary to identify the service/record and verify your request, not an identity-document copy by default. You may complain to the competent EEA authority where you live, work or where an alleged infringement occurred, or Singapore's PDPC. An operator request does not automatically erase independent provider logs, your ChatGPT history or downloaded copies.
