In brief
Perfora processes your documents exclusively on your device. The website sets no cookies and uses no analytics or advertising services. We only process personal data for hosting the website, for the licence check, for purchases via Lemon Squeezy and when you write to us.
Hosting and server logs
The website is hosted by STRATO GmbH, Otto-Ostrowski-Straße 7, 10249 Berlin, Germany, on servers in Germany. When you visit, your IP address, time, requested file, response status, browser information and, where applicable, the referring page are processed to deliver the pages and detect attacks. The legal basis is Article 6(1)(f) GDPR; our legitimate interest is secure operation. According to STRATO, IP addresses are stored for attack detection for no more than seven days.
Cookies, language and external content
The website sets no cookies and stores nothing in your browser. When you open the main address, your browser’s language setting is evaluated only on your device to open the matching language version. Fonts, images and scripts are loaded from our own server. Links to the Microsoft Store and Lemon Squeezy only connect to these providers when you click them.
Processing in the app
The PDF files you open and the files created from them are processed exclusively locally and are not transferred to us or to third parties. Files are only saved to the folder you choose in the system dialog; the source file stays unchanged. Templates contain only settings such as the split text, field labels and the structure of file names – no document content and no file paths – and are kept in local app storage. The app has no user account, no advertising and no analytics or telemetry services.
Trial period and licence check
On first launch, Perfora stores the start of the 14-day trial period locally. When you enter a licence key, the app sends it together with a neutral device name such as “Perfora (win32)” to the Lemon Squeezy License API (api.lemonsqueezy.com) to activate it. Afterwards the app checks the activation about once a day using the key and activation ID; deactivating removes the activation there. For technical reasons, Lemon Squeezy receives your IP address. Document content, file names, computer names or usage data are not transmitted. The key, activation ID and time of the last check are stored locally. The legal basis is Article 6(1)(b) GDPR. Without an internet connection, an activated licence remains valid for 30 days.
Purchase via Lemon Squeezy
You buy the licence on the Lemon Squeezy checkout page. Lemon Squeezy acts as the seller (merchant of record) and processes your name, email address, billing address and payment data under its own privacy notice; data may be transferred to the USA. We receive the order and licence key details needed for the licence, support and statutory retention obligations, but no complete payment data. The legal basis is Article 6(1)(b) and (c) GDPR.
Download via the Microsoft Store
If you download Perfora from the Microsoft Store, Microsoft processes data under its own privacy notice. We only receive aggregated statistics from Microsoft, no information about individuals.
Email support
When you write to us, we process your email address, the content of the message and any information you provide voluntarily in order to answer your request (Article 6(1)(b) or (f) GDPR). Please do not send us documents containing personal data of third parties. We use Gmail by Google Ireland Limited for the mailbox; data may be transferred to the USA, for which Google cites the EU-US Data Privacy Framework and EU standard contractual clauses. We delete completed requests six months after closing them unless a retention obligation applies.
Your rights
Subject to the legal requirements, you have the right of access, rectification, erasure, restriction of processing and data portability, and the right to object to processing based on legitimate interests (Article 21 GDPR). You can lodge a complaint with a data protection supervisory authority, for example the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia. There is no automated decision-making, including profiling.
