Privacy Policy

Effective date: September 28, 2026

This policy explains what personal information Simpli Software LLC ("we", "us") handles in providing Silo, the email marketing service at silomailpro.com (the "Service"), and how. It covers two kinds of people: customers who use Silo, and subscribers on our customers' lists.

1. Our role

• For customer account data (your sign-in, billing and usage), we are the controller.
• For subscriber data that customers upload or collect, the customer is the controller and we process it on their behalf and on their instructions. If you're a subscriber, contact the sender of the email first; we'll help them respond to your request.

2. What we store

Account data

• Name, email address, company name and hashed password, or your Google or Facebook identity if you sign in with them
• Team members, roles, invitations and the account's audit log
• Billing status and plan. Card details are handled by Stripe; we don't store card numbers.
• Your postal address, used in your email footers as the law requires
• Basic technical logs (IP address, browser, timestamps) for security and troubleshooting

Subscriber lists and content

• Email addresses, names, tags, custom fields, list membership and subscription status
• Consent records: how and when each person subscribed and, for double opt-in, when they confirmed
• Engagement data: sends, opens and clicks, bounces, complaints and unsubscribes
• Store data you connect: order counts, totals and last order date from Shopify or WooCommerce
• Your emails, templates, sequences, automations and signup pages

Encrypted credentials

Your sending credentials (Amazon SES access keys or SMTP passwords), webhook secrets and third-party API keys are encrypted at rest with a key kept separate from the database. They're decrypted only to perform the action you configured, such as sending your email. Import API keys (Mailchimp, Kit) are deleted when the import job ends.

3. How we use it

• To provide the Service: store your lists, render and send your email through your own provider, host your signup pages, record engagement and show reports
• To keep the Service secure and enforce our Acceptable Use Policy, including reviewing accounts with high bounce or complaint rates
• To bill you and to send you service messages about your account (not marketing, unless you opt in)

We don't sell personal information, and we don't use subscriber data for our own marketing or to build profiles across customers. Each account's data, including its suppression list, is kept separate from every other account's.

4. Where your email goes

Silo sends your email through the sending provider you connect (for example Amazon SES in your own AWS account, or your SMTP provider). That provider receives the messages and recipient addresses under your agreement with them; they are your processor, not ours.

5. Subprocessors

We'll update this list before adding a new subprocessor. We'll post the change on this page and email account owners at least 14 days before it takes effect.

6. This website

silomailpro.com uses a small number of cookies and similar browser storage:

• Essential: needed for the site to work, such as remembering your cookie choice. Always on.
• Analytics (Google Analytics): with your permission, shows us which pages are visited and how people find us. Google handles this data under its own privacy policy.
• Advertising (Meta Pixel): with your permission, measures whether our ads on Facebook and Instagram work, and helps us reach people who have visited our site. Meta handles this data under its own privacy policy.

Analytics and advertising cookies stay off until you allow them, and you can change your choice at any time with the Cookie settings link at the bottom of every page. If your browser sends a Global Privacy Control signal, we treat it as a request to opt out of advertising cookies. Where the law treats advertising cookies as "sharing", declining them, or sending Global Privacy Control, opts you out. Pages also load fonts from Google Fonts, which means your browser requests them from Google's servers. The app at app.silomailpro.com uses only essential cookies to keep you signed in, and has no analytics or advertising tools.

7. Security

Traffic is encrypted in transit with TLS. Credentials and secrets are encrypted at rest. Access to production systems is limited to the people who operate the Service. No system is perfectly secure; if we learn of a breach affecting your data we'll notify you as the law requires.

8. Retention and deletion

• We keep account and subscriber data while your account is open.
• When you delete a subscriber, list or other content, it's removed from the active database. Suppression entries (bounces, complaints, unsubscribes) are kept for the life of the account so those people aren't mailed again.
• When an account is closed, we delete its data within 30 days, and from backups within 30 days after that, except where we must keep records (such as billing) for legal reasons.
• Technical logs are kept for up to 30 days.

9. Your rights

Depending on where you live, you may have the right to access, correct, delete or export your personal information, or to object to or restrict its use. Customers can make requests to support@silomailpro.com. Subscribers should contact the sender of the email; every email has an unsubscribe link, and we'll pass requests we receive directly to the relevant customer. The Service is operated from the United States, and your information is processed and stored there.

10. Children

The Service is for businesses and is not directed at children under 16.

11. Changes

We'll post updates here and, for material changes, notify account owners by email or in the app before they take effect.
