Privacy Policy
Effective August 6, 2026 · Last updated August 6, 2026
This policy explains what information Killion Apps collects, why, who we share it with, and what you can ask us to do about it. It covers our website at killionapps.com and our software, including Listing Hub.
1. Who we are
Killion Apps is an independent software studio based in Phoenix, Arizona, United States. We are the party responsible for the information described here. You can reach us at killioninvestments@gmail.com.
When you use Listing Hub, you are the owner of your own shop's data and we process it on your instructions. Where the GDPR or UK GDPR applies, you are the controller of that data and we act as your processor.
2. The short version
- We collect what's needed to run your account and stage your listings, and not more.
- We connect to your sales channels using tokens you authorize. We never see or store your passwords for those channels.
- Your designs and listing data are yours. We use them to do the job you asked for.
- We do not sell personal information, and we do not use advertising or cross-site tracking.
- You can disconnect a channel, export your data, or delete your account whenever you want.
3. Information we collect
Account information
To create an account we collect your email address, a password (stored only as a salted cryptographic hash, never in readable form), your shop name, and your account and billing status. If you contact support, we keep that correspondence.
Sales channel connections
Listing Hub only works if it can reach the places you sell. When you connect a channel — a marketplace, a social platform, or a print-on-demand fulfillment provider — you are sent to that provider's own login screen and you authorize the specific permissions involved. We receive an access token, not your credentials. Tokens are stored encrypted and are used only to perform actions you have asked for.
Through those connections we access shop and catalog information needed to build and publish listings: existing listings and product records, product and variant structures, production costs and shipping costs, fee and payout structures, order and sales volume where it is used to inform pricing, and the results of publish attempts.
Designs and listing content
We store the artwork files you upload, the mockups generated from them, and the listing content built around them — titles, descriptions, tags, prices, pricing rules, placement settings, and the version history of your edits.
Payment information
Subscription payments are processed by our payment processor. We receive a customer reference, the plan, the amount, and whether the charge succeeded. We never receive or store your full card number.
Technical and usage information
Our servers log IP address, browser user agent, pages or endpoints requested, and timestamps, for security, abuse prevention, and debugging. We record application errors and the actions taken in your account so we can investigate problems and show you an audit trail of what was published and when.
What we do not collect
We do not collect your customers' names, addresses, or payment details. We do not collect precise device location, contacts, biometric identifiers, or any special-category personal data, and we ask that you not put such information into free-text fields in the app.
4. Why we process it
- To provide the service — staging, pricing, and publishing your listings, and keeping them in sync.
- To generate listing copy — drafting titles, tags, and descriptions from the design information you provide.
- To bill you — managing subscriptions and receipts.
- To support you — answering questions and diagnosing failures.
- To keep the service secure and working — detecting abuse, preventing fraud, and fixing defects.
- To meet legal obligations — tax, accounting, and lawful requests.
Where the GDPR applies, our legal bases are performance of our contract with you, your consent for optional integrations (which you may withdraw), our legitimate interest in securing and improving the service, and compliance with legal obligations.
5. Automated drafting of listing content
Listing Hub uses a third-party large language model provider to draft listing titles, tags, and descriptions. What we send is the design and product information needed for that draft — design name and description, product type, garment specs, and your own style preferences. We do not send your customer data, your account credentials, or your channel tokens. Our provider processes this to return the draft and, under our agreement, does not use it to train its models. Every draft is shown to you for review and editing before anything is published.
6. Who we share information with
We do not sell personal information and we do not share it for advertising. We share it only with service providers who help us run the software, each under contract and only for that purpose:
| Provider role | What they handle |
|---|---|
| Application hosting and database | Runs the app and stores account and listing records |
| Object storage | Stores uploaded design files and generated mockups |
| Language model provider | Drafts listing copy from product information |
| Payment processor | Handles subscription billing |
| Email delivery | Sends account and support email |
Separately, we transmit data to the sales channels and fulfillment providers you connect, because publishing your listings is the point of the service. Those platforms handle that data under their own privacy policies.
We may also disclose information if required by law or valid legal process, to protect our rights or someone's safety, or in connection with a merger or sale of the business — in which case we will tell you before your information becomes subject to a different policy.
7. Retention
| Data | Kept for |
|---|---|
| Account, designs, and listing records | While your account is active; deleted within 30 days of account deletion |
| Channel access tokens | Until you disconnect the channel or delete your account; deleted immediately on disconnect |
| Billing records | As long as tax and accounting law requires, typically 7 years |
| Server and audit logs | Up to 90 days |
| Support email | Up to 24 months |
8. Security
Data is encrypted in transit using TLS. Channel access tokens and other secrets are encrypted at rest. Access to production systems is limited to the people who operate the service and is protected by multi-factor authentication. We keep dependencies patched and we log administrative actions. No system is perfectly secure, and we will not pretend otherwise — if a breach affects your information, we will notify you and any required authority without undue delay.
9. Your rights and choices
Depending on where you live, you have some or all of the following rights: to access the personal information we hold about you, to correct it, to delete it, to receive a portable copy, to object to or restrict certain processing, to withdraw consent, and not to be discriminated against for exercising any of them.
You can do most of this yourself: disconnect a channel in settings, export your listing data, or delete your account. For anything else, email killioninvestments@gmail.com and we will respond within 30 days. If you are in the EEA or UK you may also complain to your local data protection authority. We do not sell personal information or share it for cross-context behavioral advertising, so there is no such sale to opt out of.
10. International transfers
We operate in the United States and our providers may process data there. If you are outside the US, your information will be transferred to and processed in the US. Where required, we rely on the European Commission's Standard Contractual Clauses or another lawful transfer mechanism with our providers.
11. Children
Our software is a business tool for adults and is not directed to children under 16. We do not knowingly collect personal information from children. If you believe a child has given us information, contact us and we will delete it.
12. Cookies
Our marketing website is static and sets no cookies. The application uses a single essential cookie to keep you signed in. We do not use advertising, analytics, or cross-site tracking cookies.
13. Changes
If we change this policy we will update the date at the top of this page, and for material changes we will email account holders before the change takes effect. Continued use after that means you accept the revised policy.
