Erst

Terms of service

Last updated: August 2026

The services

Erst offers perinatal fitness sessions, nutrition support, and private childbirth education in New York City, as described on this site. Booking is confirmed directly with you by email; nothing on this site creates a client relationship on its own.

Pricing and payment

Current prices are published on the pricing page and confirmed with you before any booking. Prices may change, but a confirmed booking is always honored at the agreed price.

Cancellation and rescheduling

Life with pregnancy and newborns is unpredictable — just give as much notice as you can. Sessions cancelled or rescheduled with at least 24 hours' notice carry no charge. Sessions cancelled with less than 24 hours' notice may be charged in full.

Packages

Monthly packages renew month to month. Package sessions are intended for use within the billing month and do not roll over. You can change or cancel a package with notice before the next billing month begins.

Refunds

Payments for sessions already delivered are final. If you've prepaid for sessions you can't use, we'll credit or refund the unused sessions — talk to us.

Not medical advice

Everything on this site and in our sessions is educational wellness support, not medical advice, diagnosis, or treatment. See the disclaimer for the full version.

Governing law

These terms are governed by the laws of the State of New York.
