Privacy Policy

StealthWriter · Effective September 29, 2026

StealthWriter ("we," "us") explains here what we collect when you use the StealthWriter app, why, and how long we keep it. We built StealthWriter to need as little of your data as possible — there's no sign-up, no email address, and no advertising in the app.

What We Collect

Text you submit to humanize is sent to our servers over an encrypted connection so it can be rewritten. We do not store that text — once a result is generated, only a word count is recorded against your plan's allowance. A finished result is cached on our servers for up to one hour, solely so that retrying a failed request doesn't charge you twice, and is then permanently deleted.

Your account has no email address or password. It's created automatically and identified only by an anonymous ID tied to your device's App Store purchase record (Apple's "AppTransaction"); we never see your Apple ID, name, or email. Against that anonymous ID we keep your subscription plan, renewal date, and word-usage counts.

Your drafts and the results you generate (your History) are stored only on your device — they are never uploaded to us, synced, or backed up to our servers. Deleting the app deletes them.

We automatically collect basic diagnostic information — device model, OS version, app version, and language — to keep the service compatible and to debug problems.

If you contact support from the app, we receive what you enter (such as your name, email address, and message) and use it only to reply to you.

Plan and Word-Usage Records

Your plan gives you a number of words to humanize. What each plan includes, and how words are counted, charged, renewed, and ended, is set out in our Terms of Service. To give you those words and keep your balance accurate, we keep these records against your anonymous account:

• Your plan, whether you're in a free trial or a paid period, your billing period dates, and whether your subscription is renewing, cancelled, in a billing grace period, or refunded — as reported to us by Apple.
• The words included in your current period, how many you've used or have reserved for a request in progress, any extra words added to your account, and your lifetime totals of requests and words.
• For each humanize request: its word count, when it was made, whether its words were charged or returned because the request failed, and the anonymous install ID and IP address it came from. The text you submit is never part of these records.

We use these records only to show your remaining words and renewal date, apply your plan, stop allowances being misused (for example, one plan used from many devices), and answer questions you send us about your balance.

How We Use It

We use the information above to operate StealthWriter: generate your humanized text, enforce your plan's word allowance, keep your subscription in sync with the App Store, and respond to problems you report. We do not use it to build advertising profiles, we do not sell it, and we do not share it with data brokers.

Who We Share It With

We share information only with the service providers that help run StealthWriter, each bound to use it solely to provide their service:

• A third-party AI writing partner, which receives the text you submit for the sole purpose of generating your rewritten result.
• RevenueCat, which manages subscription purchases and receives your anonymous account ID plus purchase and entitlement data.
• Apple, which processes all payments through the App Store and provides the signed purchase records we use to grant your plan.
• Analytics providers (such as PostHog and Google Analytics for Firebase), which receive anonymous usage events — screens opened, features used, word counts, error codes — so we can see what works and what breaks. Never the text you submit or receive.
• If the app asks for permission to track and you allow it, our analytics provider also receives your device's advertising identifier to measure which ads bring people to StealthWriter. Decline and everything works the same; you can change your answer any time in iOS Settings → Privacy & Security → Tracking.

We may also disclose information if required by law, or to protect the safety and rights of our users or the public. If StealthWriter is ever acquired or merged, any information we hold would transfer as part of that transaction, and we'd tell you first.

How Long We Keep It

• The text you submit: deleted immediately after your result is generated, or after at most one hour if a request is retried.
• Plan and word-usage records: kept for as long as your account exists.
• Drafts and History: kept on your device until you clear them or delete the app — we never see this data.
• Support messages: kept only as long as needed to resolve the issue.

How We Protect It

All requests to our servers are encrypted in transit, and your session is stored in the device's Keychain. No method of transmission or storage is perfectly secure, but we don't hold more than we need, so there's less at risk.

Your Choices and Rights

Because StealthWriter doesn't collect a name, email, or password, most of your data already lives on your device, under your control. Delete the app to remove all local drafts and History immediately, or ask us to delete your anonymous account and its usage data by emailing contact@heytech.work.

If you're in the European Economic Area, the UK, or California, you have additional rights under GDPR or the CCPA to access, correct, delete, or receive a copy of any personal data we hold, and to object to or restrict how we use it. We honor these requests the same way for every user, everywhere.

Children's Privacy

StealthWriter is not directed at children under 13, and we do not knowingly collect information from them. If you believe a child has used the app and shared information with us, contact us and we'll remove it.

International Use

StealthWriter is used worldwide, and the servers and service providers that process your information may be located in a different country than you are. Wherever it's processed, we apply the protections described in this policy.

Changes to This Policy

We may update this policy as the app changes. When we do, we'll update the effective date above.
