For gyms and fitness studios
Know who’s staying,
and who’s slipping away.
Memberships bill through Stripe, drop-ins and retail ring up in Square, and your promos run on Facebook and Instagram. DuckHouse brings them into one place, so you can see what memberships are worth, who cancelled and whose card failed.
Works with Stripe, Square, Meta Ads and Google Sheets.

How it works
Three steps, no data team.
You keep using the tools you have. DuckHouse gathers what they know.
1. Create a database
It runs on its own machine with its own storage. There is nothing to install.
2. Connect your tools
Sign in or paste a key for each one. DuckHouse only reads from them, brings in your history, then keeps up, as often as every 15 minutes for Stripe.
3. Ask in plain English
Connect Claude or ChatGPT to DuckHouse and ask: “Which members’ payments failed this week and haven’t been retried successfully?” It looks in your data and answers. How to connect an assistant.
What it connects
The tools you already use.
What DuckHouse brings in from each, and how you connect it.
Stripe
Members, their subscriptions and plans, invoices and charges, including the ones that failed.
Paste a read-only (restricted) key from your Stripe dashboard. New data comes in as often as every 15 minutes.
How to connect StripeSquare
Drop-ins, class packs and retail at the front desk.
Paste an access token from Square’s Developer Console. New data comes in as often as every 15 minutes.
How to connect SquareMeta Ads
What each promotion cost, by day.
Paste a system user token from Meta’s Business Settings that can read your ads. New data comes in as often as every hour.
How to connect Meta AdsGoogle Sheets
Class schedules, attendance or trainer rotas kept in a sheet.
Share the sheet with DuckHouse. Every tab becomes a table. New data comes in as often as every 15 minutes.
How to connect Google SheetsAn example
A boutique cycling studio
A made-up example, not a customer.
- 1
The owner pastes a read-only Stripe key and connects Square. Both sync every 15 minutes.
- 2
Each Monday the front desk asks for last week’s failed payments, and calls those members.
- 3
At the end of the quarter, the owner asks which start months keep members longest, before planning the next promotion.

What it costs
Pay for the hours it runs.
The smallest database is $0.0117 an hour while it runs. Left on all month with its 10 GB disk, it comes to $10.80. Set it to stop when idle and you pay for the hours it is awake, plus the disk. Data kept in object storage is $0.02 per GB a month.
Every sync wakes the database, so one synced every 15 minutes is awake most of the day. Syncing every hour, or once a day, lets it sleep in between, and you can change that per connection whenever you like.
