Contacts
A contact book for tens of thousands of addresses. Held on your device, not ours.
Import a CSV or vCard, search instantly across every field, tag and group, and export whenever you like. Tested past 25,000 contacts. There is no account and no server — the data lives in this browser.

How the storage works
Contacts are kept in IndexedDB, the browser's own database. Unlike the simpler storage most web tools use, it comfortably holds tens of thousands of records — the practical ceiling is usually your available disk space rather than any fixed limit.
The trade-off is that it's local. There's no sync between your laptop and your phone, and no copy on a server for you to recover from. That's deliberate: nobody else ever holds your contact list. But it does mean backups are your responsibility, so export regularly.
Importing
CSV with a header row is detected automatically — columns named something like name, email, tags or note are matched, and a file that's just a list of addresses works too. vCard files exported from Outlook, Apple Contacts or Google Contacts are read directly. Duplicates are matched on the email address and skipped.
Exporting
Export writes a CSV containing everything, which imports into Gmail Contacts, Outlook, or any CRM. The JSON export is a complete backup including tags and notes, and can be imported straight back here.
What the email contacts manager does
Contacts is a free address book that lives in your web browser. You can import a large list, search it in an instant, tag people into groups and export it again whenever you need to. There is no account to create, and your list stays on your own device instead of on someone else's server.
Benefits
- Import from the files you already haveBring in a CSV, a tab or semicolon separated file, a vCard, or a plain list of addresses. Names written like "Jane Doe <[email protected]>" are picked up too.
- No duplicate clutterWhen you import, any address already in your list is skipped, and the tool tells you how many were added and how many were skipped.
- Search everything at onceOne search box looks through names, email addresses, domains, tags and notes as you type.
- Tags for simple groupsGive contacts one or more tags, such as "clients" or "suppliers", then filter the list to a single tag.
- Sort and page through big listsClick a column heading to sort by name, email, domain or tags. Results show 100 at a time with page buttons.
- Quick counts at the topSee how many contacts you have, how many match your search, and how many different domains and tags are in the list.
- Three ways to exportDownload a CSV for spreadsheets and other apps, a vCard file for address books, or a JSON backup that keeps tags and notes and can be imported back here.
- Backup remindersThe tool remembers when you last exported and nudges you to download a backup if it has been a week or more.
Who it is for
- Small business owners who want one tidy customer list without paying for a CRM.
- Freelancers keeping track of clients and leads, tagged by project or status.
- Event and club organizers managing member or attendee email lists.
- People moving contacts between Gmail, Outlook and Apple Contacts who want to clean and merge them first.

Your privacy
Your contacts are saved in this browser's own storage on this device and are never sent to ListaFix or any server. Because nothing is stored online, clearing your browsing data erases the list, so keep an exported backup.
Common questions
Where are my contacts stored?
In this browser on this device, using IndexedDB — the browser's own database. Nothing is sent to a server and there is no account.
How many contacts can it hold?
Tens of thousands comfortably; it's been built and tested past 25,000. The practical ceiling is your available disk space rather than any fixed limit, unlike the simpler storage most web tools use.
What happens if I clear my browsing data?
Your contacts are erased. There is no sync and no copy on a server to recover from. That's the trade-off for nobody else holding your list, and it makes the export button a backup rather than a convenience — use it regularly.
Can I import from Gmail, Outlook or Apple Contacts?
Yes. Google Contacts CSV, Outlook CSV and vCard exports are all read directly, including names, groups and notes where present. A plain list of addresses works too. Duplicates are matched on the email address and skipped.
Can I use this on my phone and my laptop?
Not as one shared list. The data lives in a single browser on a single device. You can export from one and import into the other, but there's no automatic sync.
