Educational use only

Everything on this site is general information. It is not medical advice and it does not create a doctor-patient relationship. Do not use it to diagnose or treat a condition. Talk to your doctor or pharmacist before you change your diet, activity or supplements, especially if you take medication, are pregnant, or have a health condition.

Subscriptions on the web

Midline on the web (app.midlineplan.com) is sold by Aayla Secura LLC (dba Sarvixo) and billed through Stripe. Charges show on your card statement as SARVIXO.

• Plans. Yearly: $59.99 a year. Monthly: $9.99 a month. Prices are in US dollars.
• Free days. Midline is free for 14 days from the day you finish setup. If you finished setup before November 12, 2026, your 14 days start the first day you open Midline on or after that date. No card and no account. On day 15 it asks you to pick a plan to keep using it. You’re only charged if you pick one.
• Charges. Both plans are charged the day you subscribe, and again each year or month until you cancel. That’s true even if you subscribe during your free days.
• Earlier yearly trials. If you started the 7-day free trial on the yearly plan before we switched to 14 free days, it works as it did: you’re charged $59.99 on day 8 unless you cancel.
• Auto-renewal. Your plan renews automatically at the end of each year or month, and you’re charged again each time, until you cancel.
• How to cancel. In Midline, go to Settings, then Manage subscription, then Cancel plan. Or email ryan@sarvixo.co and we’ll cancel it for you. You keep Midline until the end of the time you paid for.
• Refunds. If you were charged and didn’t mean to be, email ryan@sarvixo.co within 14 days of the charge and we’ll refund it.
• Price changes. If the price changes, we’ll email you before you’re charged the new price, so you can cancel first.
• Your Midline link. After you subscribe, Midline gives you a private link that brings your subscription back in any browser. Anyone with it can manage your subscription, so keep it to yourself.

Free tools

Calculators give a rough guide from what you type. They are not a diagnosis and they do not suit everyone. They run in your browser and we do not store what you enter.

The app launch email

Joining the list means you agree to get an email when the Midline iPhone and Android apps launch. It isn’t a purchase, and it doesn’t reserve a price, a plan or a place in the apps. You can ask us to remove you at any time. See the privacy policy.

Sources and links

We link to outside sources and are not responsible for their content. Articles show when they were last reviewed, and information can go out of date.

No warranty

The site is provided as is. To the extent the law allows, Midline is not liable for losses from using it or relying on it.

Changes and contact

We may update these terms and will change the date above when we do. Questions: ryan@sarvixo.co.
