Stacy is designed in India and manufactured in ISO 9001:2000 certified facilities in China. Every design decision — the 105° flange angle, the five flange sizes from 15mm to 24mm, and the medical-grade silicone — is grounded in the biomechanics of breastfeeding and built around how mothers' bodies actually work.

All parts that come into contact with skin and milk are made from medical-grade silicone — BPA-free, skin-safe, and body-temperature responsive. The pump body is made from food-grade ABS plastic. Every milk-contact part is dishwasher-safe.

Yes. Stacy is FDA approved and ISO certified, meeting international standards for safety and hygiene. Manufacturing takes place in ISO 9001:2000 certified facilities in China. All materials are tested to applicable safety standards.

Because nipple anatomy varies significantly between individuals. The standard industry approach of shipping one or two sizes leaves a large proportion of mothers pumping in a size that doesn't fit their anatomy — causing discomfort, reducing milk output, and over time contributing to supply decline.

Stacy ships with five sizes — 15mm, 17mm, 19mm, 21mm, and 24mm — along with a printed nipple size guide in every box. This is not a marketing feature. It is a clinical decision rooted in the reality that fit is the most important variable in pumping comfort and output.

Standard pumps use a 90° flange angle — a straight tunnel that requires the user to lean forward for milk to flow. Stacy's 105° angle allows the mom to sit fully upright. Milk flows downward with gravity naturally, without any postural adjustment.

The practical effect: sessions are more comfortable, last longer, and drain the breast more completely. Complete drainage is the single most important signal your body uses to maintain milk supply.

Optional — but genuinely useful. The app gives you hands-free control over suction levels and modes, and automatically logs each session. Most moms who use it find that the session data helps them understand their supply patterns and spot when frequency is dropping. It is included with every Stacy pump at no additional cost.

Each pump has a different strength. Spectra S1 delivers very strong suction and is a trusted choice for moms who pump at home. Momcozy M5 is wearable and discreet. Medela Swing is a reliable single-side corded option with a long track record.

Stacy is the only wearable pump in India that combines five flange sizes, a 105° ergonomic angle, medical-grade silicone, and an integrated app. If fit, comfort, and daily convenience are your priority — Stacy is the more complete solution.

Every Stacy box includes all five flange sizes and a nipple size guide to help you find the right fit immediately. You do not need to purchase additional sizes separately. If you are still unsure, reach out to us at hello@stacy.care — our support team can help you identify the correct size based on your measurements.

The rechargeable battery lasts up to 7 full pumping sessions on a single charge. Stacy charges via USB-C and takes approximately 2 hours for a full charge.

No pump is right for every mom. If you need the highest possible suction output and portability is not a priority, a hospital-grade corded pump may serve you better. If you have specific medical needs, please consult your lactation consultant or doctor before choosing any pump.

Stacy is designed for moms who want a wearable, comfortable, well-fitted pump that works with their body and fits into their daily life. If that describes you, we believe Stacy is the best option available in India today.

Stacy comes with a 1-year full refund guarantee — if the motor stops working within the first year with no water exposure, we offer a 100% refund. Additionally, any part that becomes non-functional due to manufacturing or performance issues is replaced free of charge for 3 years.
