How long does switching from Cloze actually take?

An evening for most accounts. The export from Cloze is the slow step - the import side runs in minutes once the field mapping is settled. Larger teams (50+ seats with custom field schemas) sometimes split it across two sessions: import first, reorganise the next day.

Will I lose data when I switch?

Nothing structural. The CSV/JSON export from Cloze preserves the data: records, fields, history, and attachments come over intact. What doesn't transfer is anything tied to Cloze-specific UI metadata (custom views, saved searches, in-app annotations) - those don't sit in the export, they sit in the source product's UI. Plan an evening to rebuild your most-used views once you're in.

What about my existing Cloze subscription?

Run both side-by-side until you're confident, then cancel Cloze from their side. We don't lock you in - export from Contact Book is one click in account settings, same as import.

Is the import path free?

The import button is open on every plan, including the free tier - we don't paywall the way out of a competitor. The data going in still has to fit your plan's per-type quotas (the free-tier caps are listed on /sales); paid plans raise those caps. If you're moving a large set, check the caps first or write to /support and we can advise.

Can I get help with the switch?

Yes. Write to /support - both founders see those threads directly. Reply within a working day. For the field-mapping itself we typically resolve things in one or two exchanges; if your dataset is unusually large or Cloze's export shape is unfamiliar, we'll say so up front.

Contact Book is what people use when Cloze stops fitting. Below is the honest side-by-side - same product surface, different posture: hosted in Germany, no third-party trackers, one honest price - plus the migration mechanics that decide whether the switch lands in an evening or in a quarter.

At a glance

Cloze ingests your email + calendar + social and uses AI to surface contacts you should reach out to. Contact Book is the opposite - it expects you to log meaningful interactions deliberately, and trades AI surfacing for a calmer, more private system. If you want a relationship intelligence engine that watches your inbox, Cloze is the obvious pick. If you want a personal CRM that does not read your email, that's exactly what we are.

Switching

What moving from Cloze actually looks like

The switch goes in three rough phases: export from Cloze, import into Contact Book, and reorganise what came over. Most people allocate an evening for it. The export side is where the time goes - Cloze hands you a CSV/JSON dump and the field mapping isn't always obvious; once that's resolved the import is a couple of minutes. We don't paywall the import path or pretend it's a pro-only feature, and you can run both side-by-side while you decide.

When to pick which

Pick Contact Book when

You don't want a tool that reads your email - even if it would surface useful prompts.

Manual entry suits you - typing in what mattered is the moment that helps you remember.

Hosted in Germany matters; you don't want US-headquartered infrastructure for your inbox-adjacent data.

Pick Cloze when

You'd genuinely use the AI suggestions and want a tool that watches your channels.

Sales-style relationship scoring helps you prioritise.

Inbox + calendar + social ingest is the killer feature for you.

Step by step

Export from Cloze

Find the export option in Cloze's account settings. Most tools provide a CSV or JSON download. Save the dump locally - that's the source of truth for the next step.

Account settings → Export / Download data

Pick the broadest format the tool offers (usually JSON)

Map fields in Contact Book

Open the import tool in Contact Book. Cloze's field names rarely match Contact Book' 1:1; the import flags any unmapped columns so you can pair them up before anything commits.

Account settings → Import

Resolve the mapping prompts the tool surfaces

Run the import

Run the import. Contact Book shows a preview of the first parsed rows in the import dialog so you can sanity-check the column mapping + a sample of records before anything commits. If you're nervous about a large dump, import a small subset first, verify it landed the way you expected, then run the full file.

Re-create your views, tags, saved searches

Cloze-specific UI metadata (custom views, saved filters, in-app annotations) doesn't transfer with the data export. Spend an evening rebuilding the views you used most - usually a 30-minute job once you've done it once.

Cancel Cloze when you're confident

Run both side-by-side for a couple of weeks if you want to be sure. When you're confident, cancel the Cloze subscription from their side. Contact Book keeps your export option self-serve in account settings - no lock-in either direction.
