Your account
Your Tachyn account holds your plan and subscription. You sign in, upgrade and manage billing from the app; payments and invoices are handled by Stripe.
Sign in
In Tachyn, open Settings, then Account, and choose Sign in. Your browser opens with a one-time code already filled in: confirm it and the app is signed in. The app never stores a password.
Download for MacUpgrade to Pro
Settings, then Account, shows your plan, trial days left and this week's words. Choose monthly or yearly there, and Stripe Checkout opens for your signed-in account.
Compare plansManage or cancel
Choose Manage subscription in the same place to change plan, update your card, download invoices or cancel. Cancelling takes effect at the end of the period you paid for.
Email us insteadJust subscribed?
Thank you. Your plan changes as soon as Stripe confirms the payment, usually within a few seconds; the app shows it the next time you open Account.
Delete your account
In Tachyn, open Settings, then Account, then Delete account, and confirm. Cancel any subscription first (Manage subscription). Deleting removes your account, your usage records and your sign-in at once, and cannot be undone; billing and tax records are kept as the Privacy Policy sets out. Your history on your Mac stays until you remove the app. No app? Email hi@tachyn.ai from your account's email address and we delete it for you.
