A little more clarity.
A little less to figure out.

Cayn is a proactive financial assistant for individuals, landlords and property managers. It brings your bank accounts, receipts, bills and rental records together, flags changes and prepares work for you to review.

There are two plan categories: Individuals, with Personal and Personal Plus; and Landlords & property managers, with Rental and Rental Plus. Rental plans include personal-finance features as well as property tools. Compare the plans.

Yes. Personal plans cover everyday accounts, receipts, bills and the assistant. You only need a Rental plan if you want the property, tenant, rent and rental-document features.

Open the Cayn web app, or download Cayn for Android or iOS. Create your account and choose a plan. No download is needed for the web app. Then add the records you want to organize, connect a bank account or import transactions, and scan receipts. You can add rental properties with a Rental plan.

Yes. Cayn is available in your browser at cayn.ai/app, on Android and on iOS. Sign in with the same Cayn account to access your records across platforms.

No. You can use manual accounts and transactions or import supported CSV files. A bank connection brings in transactions and balances and gives Cayn more information for matching receipts and spotting changes.

No. Bank connections are read-only. Cayn organizes financial records, tracks payments and highlights changes; it does not transfer money or pay bills on your behalf.

No. Connecting Gmail is optional. Its read-only access lets Cayn find financial and rental emails, such as receipts, bills and tenant inquiries. Cayn cannot send, change or delete email through that connection. You can scan receipts directly without Gmail.

Cayn reads the receipt and looks for a matching transaction. When a match is available, it compares the receipt with the posted charge and flags differences for review, including relevant item, tax and tip details. Matching depends on the records available.

Cayn organizes items from your receipts and remembers what you paid over time and across stores. Where items and units are comparable, it helps you compare the prices in your own purchase history.

Keep properties, units, tenants, leases, rent and expenses together. Cayn helps match payments to rent cycles, find rental expenses in transactions and receipts, prepare leases and checklists, and organize income and expenses by property for Schedule E.

Rental includes up to 5 units and Rental Plus includes up to 15. Both include unlimited tenant records within the plan’s unit limit. See pricing for the full allowances, including signed contracts, receipt scans and assistant questions.

Cayn tracks rent and helps match recorded payments to tenants and rent cycles. Rent collection and money transfers are not included in the current release.

Cayn researches state, county and city rental requirements and connects them to your property’s location. Topics include leases, notices, deposits, fees and disclosures. You can review the sources behind the guidance. Coverage varies by location and topic.

Review the source links, property details and the terms of the relevant lease. Requirements can depend on the property, tenancy, dates and exceptions. Cayn helps organize that information and prepare the next step; you review the details before sending a document.

Cayn looks for changes in the records you provide, such as a recurring bill increase, a receipt that differs from its charge or overdue rent. It brings things needing attention into view so you do not have to ask about every record individually.

Ask about spending, transactions, receipts or bills. With a Rental plan, you can also ask about your properties, rent and tenant records or request help preparing supported rental work. Cayn uses the records and features available in your account.

The assistant prepares supported changes for you to review. Actions such as sending a lease, checklist or notice wait for your review and approval. Reading records to answer your question does not require an approval card.

Review and edit the record in the app where editing is supported. You can also give feedback on an assistant answer or contact Support. Check the underlying amounts, dates and documents before approving important changes.

Choose Personal or Personal Plus for everyday finances, or Rental or Rental Plus for personal finances and rental work. Monthly and yearly options are listed on pricing, alongside each plan’s allowances. Review the price and renewal terms shown at checkout.

Eligible households can choose a 14-day trial on Personal or Rental. Personal Plus and Rental Plus start with a paid subscription. One trial is available per household, and the store account’s offer eligibility also applies. Review the trial and renewal terms before confirming.

Yes. Up to 5 people can share one plan, with allowances pooled across the household. Members join the owner’s plan rather than buying a second subscription. Shared access means working in the household’s shared workspace.

No. Rental plans include personal-finance features. Rental Plus includes the Personal Plus features as well as rental tools and higher allowances. Choose the single plan that fits your household’s needs.

Use the service that bills you: the App Store for Apple purchases, Google Play for Google purchases, or Cayn web billing for subscriptions purchased on cayn.ai. Canceling renewal keeps access through the period you paid for.

Cayn notifies you and keeps saved records for a 90-day recovery period before deletion. You can export saved records during that period, and renewing before deletion keeps them. This is separate from requesting account deletion. See the retention details.

No. Bank connections use our financial-data provider, Plaid. Cayn stores connection tokens on its servers rather than your bank login credentials. You authorize the connection and can disconnect it.

We do not sell your personal information. Cayn may use your information, with details such as account numbers removed, to train and improve its AI unless you turn this off in Settings → Privacy → Help improve Cayn. Gmail data and health information are never used for training. Service providers process information needed for the features you use and may not use it to train their own models. If you give assistant feedback, a conversation may be retained to investigate mistakes; sharing controls are available in Settings. See our Privacy Policy for details.

Use Delete Cayn Account in the app’s account settings and confirm your request. If you cannot use the app, follow the account-deletion instructions. Cancel any store subscription separately with the service that bills you.

Open Support in Cayn to send a report and follow replies in the app. You can also use our contact page or email contact@cayn.ai. Never send passwords, sign-in codes or bank credentials.
