Privacy

Booklet Imposer processes your PDF in your browser. We do not upload the file body to our servers. Network requests during impose and export should show no user-file PUT or POST. We do not run accounts. Settings stored on this device use the key prefix booklet-imposer.v1 and never include PDF bytes or filenames. If ads are enabled by the operator, AdSense may use cookies after you choose Allow ads. Optional Plausible analytics, if configured, receives events without filenames. We do not sell personal information. We do not store your PDFs.

v1 settings keys include units, paper, custom sheet size, gutter, total creep, bleed, mixed-fit mode, preview and export mark toggles, rotate-backs, last preset, and ads consent. Quota failure shows a toast; you can still impose. Last-write-wins across tabs for settings only. There is no beforeunload warning. Samples under /examples/ are public-domain files we ship, not your documents.

Error codes we may record in optional analytics: not_pdf, empty, encrypted, invalid_pdf, too_large, too_many_pages, oom, unsupported_browser, embed_failed, cancelled, unknown. Size and duration are buckets, never raw bytes or filenames. Contact is email. This policy is for a 13+ audience and is not child-directed.
