How to Track Subscription Renewals and Bills on Your Family Calendar

That surprise $99 charge for a subscription you forgot about is the worst. Stop tracking renewals in spreadsheets and get them automatically on the calendar your whole family already uses.

Important Dates Shouldn't Live in Spreadsheets

How many times have you been surprised by an insurance renewal? Or forgotten when your car registration expires? EstateHelm already tracks these dates for you—now you can have them automatically appear in your personal, shared, or family calendar.

Insurance Renewals

Home, auto, life, and health insurance renewal dates

Subscription Charges

Netflix, gym memberships, software licenses

Service Appointments

HVAC maintenance, pest control, lawn care

Warranty Expirations

Appliance warranties and return deadlines

Tip: You can email your subscription receipts to [email protected] and we'll automatically extract the details. Learn more about email import.

How It Works

Calendar Sync uses the iCal standard—the same format used by Google Calendar, Apple Calendar, Outlook, and virtually every calendar app. Simply enable the feature, copy your unique feed URL, and subscribe from your calendar app.

Three Simple Steps

  • 1
    Enable Calendar Sync in your EstateHelm settings
  • 2
    Copy your unique feed URL—it includes an encryption key that only you have
  • 3
    Add it to your calendar app as a subscription (Google Calendar, Apple Calendar, Outlook, etc.)

Your calendar will automatically refresh and show your upcoming events. Toggle which event types you want to sync—insurance, subscriptions, services, maintenance, or valuables.

Encrypted at Rest

Your calendar data is encrypted on our servers. We can't read your feed without the key that's embedded in your unique URL. Learn more about our security.

AES-256-GCM Encryption at Rest

Your calendar feed is stored encrypted on our servers. The data is meaningless without the decryption key.

Key in Your URL

The decryption key is embedded in your feed URL. We only decrypt the data when your calendar app requests it with the correct key.

Zero Knowledge Storage

Without your URL, we cannot read your calendar feed. Our servers store only encrypted data.

How the Encryption Works

Your EstateHelm Events
↓ Encrypted with AES-256-GCM
Encrypted Calendar Feed (stored on server)
↓ Calendar app requests feed with key in URL
Server decrypts on-the-fly
↓ Plain ICS delivered over HTTPS
Your Calendar App

When you enable Calendar Sync, a unique AES-256 encryption key is generated in your browser and embedded in your feed URL. Your calendar data is encrypted before being saved to our servers. When your calendar app requests the feed, our server decrypts it on-the-fly and delivers standard ICS format over HTTPS.

Why this matters: Your data sits encrypted on our servers. Without your URL, we cannot read it. This protects against data breaches—even if someone accessed our database, your calendar data would be unreadable without the keys embedded in your URLs.

Important Considerations

While we've made Calendar Sync as secure as possible, there are inherent limitations to the iCal standard that you should understand:

Your URL is your key

Anyone with your feed URL can view your calendar events. Treat it like a password—don't share it or post it publicly.

Event titles only

Calendar feeds only include event titles and dates. Sensitive details like account numbers or credentials are never included in calendar events.

You control what syncs

Choose exactly which event types to include. Skip anything you'd rather not have in your calendar.

Regenerate anytime

If you ever suspect your URL was compromised, simply delete the feed and create a new one. The old URL will immediately stop working.

No URL logging

We don't log feed URL requests. Your decryption key passes through our servers only in memory during the request and is never stored or logged.
