Privacy policy
How ERITHRA tools handle files, browser processing, and external services.
File and text processing
Image, PDF, text, developer, and media operations run in your browser. ERITHRA does not upload those selected files to an application server. Your browser can use temporary memory or disk cache during processing. Results are lost when you close the tab unless you download them. Do not use a shared device for sensitive content without considering that device’s security.
External requests
Currency conversion requests dated public rates from Frankfurter, normally through a Cloudflare Pages Function, with a direct provider fallback. Requests contain currency codes, not the amount you enter. Thumbnail viewing loads public images from YouTube’s image servers, which receive the request and ordinary network information. Links you open lead to services with their own privacy policies.
Speech features
Speech recognition requires microphone permission and may send audio to your browser vendor’s recognition service. Text-to-speech may use local or network voices. The voice selector identifies voices reported by the browser as local. ERITHRA does not record or retain speech on its servers.
Storage, analytics, and advertising
No analytics network is configured. Google AdSense publisher verification code is included in the shared page head. Google may receive ordinary network and browser information when its script loads and may use cookies or similar technologies under its policies. Manual ad units remain disabled; verification does not mean Google has approved the site. ERITHRA itself sets no application cookies. Browser localStorage remembers appearance, favorite tool slugs, the last twelve tool slugs visited, and selected non-content tool options such as format, dimensions, and quality. It does not save uploaded files, pasted text, generated passwords, dates, or finance amounts. Currency reference rates can be cached in sessionStorage for the current tab session, with their source date retained. The Cookies & preferences page lets you clear saved preferences and disable tool-option remembering. These choices are specific to this browser and website address.
Temporary download transfers
Selecting a generated download can move its finished file to a separate download page using IndexedDB in this browser. This does not upload the file to ERITHRA. The transfer copy is removed when the download page restores it. Unopened transfers expire after ten minutes and are purged on the next download operation. Closing the browser can leave an unopened transfer stored locally until that cleanup or until you clear website data. The download page holds its file in memory until closed or reloaded. When browser storage is unavailable, the original direct download is used instead. Tool preference storage remains separate and does not contain these files.
Hosting and contact
Production hosting is migrating to Cloudflare Pages from Netlify, which may process network information and access logs under its service policies. This policy does not make promises about infrastructure-level retention. The owner’s contact channel is listed on the contact page when configured. Tool links share the page address only; files and entered values are not included. Directory search terms can appear in its URL, so avoid entering personal information into a search query.
Changes
Last updated: 29 October 2026. The owner should review this policy, its contact information, and applicable obligations before production launch and whenever services change.
