Private, by the way it works.
Most PDF and image tools process documents in your browser. Office-to-PDF, HTML-to-PDF and PDF/A conversion use a temporary server upload, only after you select the upload checkbox and start conversion. The optional AI assistant sends reviewed, extracted text to the provider named in the tool only with your confirmation.
What happens to your documents
For browser-local PDF and image tools, the file you choose is read into browser memory. Processing and rendering happen on your device. Downloads are created locally. Closing the tab releases the working session; your original files and any downloads stay wherever you saved them.
Temporary conversion uploads
Office, HTML and PDF/A conversion files are uploaded to this site and processed by its dedicated LibreOffice worker. PDF/A outputs are also checked by veraPDF. HTML scripts and external resources are removed. These files are not sent to an external AI provider. The worker deletes temporary input, output and profile files after processing, including ordinary errors and cancellation. After a crash, stale scratch directories are swept after one hour while the worker is running. No conversion history or permanent result URL is stored.
The PDF download is held in browser memory after conversion. Avoid sensitive uploads on shared or untrusted deployments. Hosting operators control their own logs, disk snapshots and backups; this code does not guarantee secure disk erasure.
What this site stores
The optional offline toolkit saves only its app scripts, icons and styles in browser Cache Storage. Documents and outputs are never added to that cache. Use Remove saved toolkit to clear it. Only the four tools listed in that toolkit work offline.
Favorites, recently used tool names and saved workflow steps are stored in localStorage on this browser. Document contents, document names and passwords are not saved there. Clearing site data in your browser removes these preferences.
This site has no account system or advertising pixels. Optional Google Analytics is described below. The hosting provider receives ordinary page requests, including IP addresses and request headers, according to its logging configuration. This is separate from document processing.
Optional Google Analytics and cookies
We use Google Analytics 4 only after you choose Allow analytics. Reject analytics is equally available, and every tool works without analytics consent. Before consent, the Analytics script is not loaded and no Analytics measurement requests are sent. Advertising storage, advertising user data, personalization and Google signals remain disabled.
After consent, Google receives page visits to known public pages, page titles, cookie identifiers and technical browser/device information. Requests also expose your IP address to Google for processing. We send only recognized search-engine referrer origins, without their paths or queries. We exclude document contents, filenames, passwords, entered form values, site-search terms, URL query parameters and fragments. Automatic form, outbound-link, search and file-download measurement is disabled.
The first-party cookies _ga and _ga_MEJHY5S0YN distinguish visits and sessions. We configure a maximum 180-day cookie lifetime without extending it on each visit. Your consent choice is stored in localStorage for up to 180 days. Analytics user/event retention is configured to two months; aggregated reporting may be retained longer. Google may process data outside your country. See Google’s privacy policy and how Google uses information from partner sites.
Use Analytics preferences in the footer to change or withdraw consent. Rejecting stops future measurement and removes this site’s Analytics cookies; it does not undo data already received by Google. You can also clear this site’s browser data or use Google’s Analytics opt-out add-on. Analytics is limited to paperlumo.com and is disabled on temporary previews.
Resources and connections
Fonts, PDF libraries, processing engines and English/Hindi OCR models are served from this site and downloaded when needed. Passwords are used in memory for Protect and Unlock PDF; they are not sent to our server. The optional AI assistant sends extracted text to this server and then to the AI provider named in the tool after you explicitly confirm. This app does not persist the submitted text or AI results. Cancelling does not undo text already received by the provider. Office conversion uses this site’s dedicated worker, as explained above. Additional planned capabilities are listed on our roadmap.
The current AI provider is Groq. Groq says ordinary inference inputs and outputs are not retained by default, but may be logged for system reliability or abuse investigations for up to 30 days, or longer where legally required. Usage metadata is retained. Groq states that retained customer data is stored in the United States. Read Groq’s data policy. The free account has token and request limits. This site does not automatically switch to a paid model when a limit is reached.
Understand each tool’s limits
Removing metadata is not the same as sanitizing a whole document. Cropping hides content but does not delete it. Redaction rebuilds the document as images and does not carry over the original text layer. Review exported pages before sharing sensitive information.
Editing can invalidate an existing digital signature. Typed signatures are visible marks, not certificate-backed signatures or identity verification. We do not claim ISO certification, a compliance audit, or protection from a compromised browser or device.
