Worth Buying? · Data & advertising

Information saved on this device

Item names, prices, frequency, months, target cost and currency are saved automatically in browser storage, along with up to five named comparisons. Korean and English storage are separate. There is no cross-device sync or server upload of calculation inputs.

Deletion and save failures

Deleting a saved comparison removes that named copy, not the current inputs. To remove all drafts and saved comparisons, clear this site’s browser data; this can be irreversible. If storage is unavailable, keep needed details elsewhere before closing the page.

Sharing and external links

The tool-share action sends only the website address, without item names, prices or comparisons. Screenshots or text you copy yourself reveal the contents to your chosen recipients. External sellers apply their own data policies.

Hosting, optional counts and support

Hosting may process basic connection information. Optional anonymous counts are off by default; when allowed, only daily site, language and action totals are recorded. Calculation inputs and personal identifiers are not included in those counts.

Affiliate offers disclose commissions. Submitting a support request uses the retention information shown there. Do not submit payment information.
