Privacy and data
Parimere is published by Sunaissu. This page describes the public web app at parimere.sunaissu.com and the separately installed Android app. Updated October 27, 2026.
Your comparisons
Parimere stores your open and saved comparisons, product catalog and history, preferences, scenarios and cached exchange rates on your device. These stay until you erase them, clear browser/app storage, or uninstall the Android app. Browser storage can also be cleared by your browser.
Selected receipt and label images are processed on your device for English text or barcode recognition. Parimere does not upload those images. The image and extracted text stay in memory during review. A price you accept becomes part of the comparison.
Android app
The initial Android build has no accounts, household sharing, automatic exchange-rate requests, ads, billing or analytics SDK. Enter exchange rates yourself. Its calculation and scanning files are bundled with the app. Android backup is disabled for app data.
When you export a file, Android lets you choose an app or location to receive it. That destination handles the copy under its own rules. Temporary export files are kept in the app cache, removed after 24 hours on a subsequent startup, or removed when you erase local data. Copies you save or share elsewhere remain until you delete them there.
Web app
Automatic exchange rates request currency pairs from api.frankfurter.dev. These requests include currency codes and ordinary network information needed to deliver a response; they do not include product names, prices, notes or photos. Frankfurter states that its API does not retain personal data, IP addresses or request URLs. See Frankfurter's information about its service. You can enter a manual exchange rate instead.
The public website is delivered through Cloudflare. Cloudflare processes network and request information to deliver and protect the website under its privacy policy. Its processing and retention are governed by that policy. Parimere does not add advertising or analytics scripts.
Your device's language and region settings suggest the initial currency. Parimere does not request GPS permission. You can change the currency at any time. The public static web release has no accounts or household-sharing service. Optional sharing in separately hosted installations is governed by that host's policy.
Offline use stores app files in this browser. Exporting or sharing a file creates a copy at the destination you choose. Those copies remain until you or the recipient removes them.
Erase data
Open All tools, then Data on this device, and choose Delete all local data. It removes local comparisons, history, preferences and cached app files on this device. It cannot remove copies already exported or shared to other devices. Clearing the current comparison alone does not erase saved data. Export a backup before changing browser, device or website domain.
Support and privacy questions
You can report a problem or ask a question on GitHub. GitHub requires an account to post, and issues are public. Do not attach private comparisons, photos, exports, credentials or other personal information. If your question needs a private response, ask for a private contact method without posting sensitive details. GitHub handles information submitted there under its own policies.
