Cookie Policy

Last updated: August 11, 2026

This Cookie Policy explains how Sezi LLC, doing business as SimpleTextToSpeech.io ("we", "us", "our") uses cookies and similar storage technologies on our website at https://simpletexttospeech.io (the "Service"). The short version: we set one first-party analytics cookie (ph_*_posthog) so we can see how the site is used and, when paid search campaigns are active, Google Ads measurement cookies so we can tell which ads actually lead to a purchase. We honor your browser’s Do Not Track and Global Privacy Control signals as opt-out for both. No retargeting, no third-party sharing, and no ad tags at all while no campaign is running. The slightly longer version is below.

1. What Are Cookies?

Cookies are small text files stored on your device by your web browser when you visit a website. They are commonly used to remember preferences, keep you logged in, or track you across sites. Browsers also offer related storage mechanisms such as localStorage, sessionStorage, and IndexedDB.

2. Cookies We Set

We set exactly one first-party cookie, used purely for product analytics:

CookieDomainPurposeLifetimeType
ph_<projectKey>_posthogsimpletexttospeech.ioAnonymous visitor ID used by PostHog so we can stitch a single visitor’s page views together across subdomains and across page reloads (see our Privacy Policy Section 1.8 for the full description). Set as a first-party cookie on the apex so the visitor ID survives www → apex redirects without restitching the session.~1 year (PostHog rotates)Analytics
_gcl_* / Google Ads cookiessimpletexttospeech.io and google.comSet only while a paid search campaign is active. Google’s measurement tag (gtag) uses these to attribute a purchase back to the ad that brought you here, so we can tell which keywords are worth paying for. Measurement only: we do not run retargeting or build advertising audiences. See Google’s cookie policy.Up to 90 daysAdvertising measurement

We do not set any other first-party cookies. There is no login or account, so there is nothing else to remember between visits. The Google Ads row is conditional: while no campaign is running, the tag is not loaded and none of those cookies are set.

3. Browser Storage We Use

KeyPurposeLifetimeType
simple-tts:workspace-v2sessionStorage: remembers your in-progress text and selected voice so a page refresh doesn’t lose your workCleared when you close the browser tabStrictly necessary
ph_*_posthoglocalStorage: session metadata, replay buffer, and feature-flag cache used by PostHog. Backs the larger replay payload that wouldn’t fit in a cookie. Mirrors the visitor ID stored in the cookie of the same name (see Section 2)Persists until you clear it (or until PostHog rotates it)Analytics

The workspace data lives entirely on your device. The text is only sent to our servers when you deliberately request a free preview or submit the project for paid synthesis; closing the tab without doing either leaves nothing behind. The PostHog visitor ID is sent to our analytics provider on every page view; if your browser sends a Do Not Track or Global Privacy Control signal, the PostHog SDK short-circuits and nothing is collected. You can clear all of this at any time via your browser’s site-data controls.

4. Third-Party Cookies

4.1 Cloudflare (CDN & security)

Our website is served through Cloudflare. To protect the site from automated abuse and DDoS traffic, Cloudflare may set a strictly-necessary cookie called __cf_bm (and, in some cases, _cfuvid) on your browser. These cookies do not identify individual users and are not used for advertising. See Cloudflare’s cookie reference for details.

4.2 Stripe (when you check out)

When you click "Pay & generate", you are redirected to a hosted Stripe Checkout page on Stripe’s domain. Stripe sets its own cookies on that page for fraud prevention and session management; those cookies are governed by Stripe’s privacy policy. We do not embed the Stripe SDK on our own site.

5. What We Don’t Use

To be clear about what we do not do:

  • No retargeting pixels, no advertising audiences built from your visit, and no programmatic-ads tags beyond the Google Ads conversion measurement described in Section 2
  • No social media cookies or widgets
  • No fingerprinting, supercookies, or cross-site tracking
  • No third-party analytics other than PostHog (described in Section 2 above and Section 1.8 of our Privacy Policy)

The PostHog session replay does record mouse movements, scrolls, and clicks on this site, but every form input is masked by default, so the text you type into the workspace, your email at checkout, and any other typed content are not captured.

6. How To Opt Out

The analytics cookie described in Section 2 is the only thing on SimpleTextToSpeech.io that isn’t strictly necessary. We honor three opt-out paths, any one of which fully stops SimpleTextToSpeech.io from collecting analytics from your visit:

  1. Enable Do Not Track (DNT) in your browser. The PostHog SDK detects DNT and short-circuits before any cookie is set or any event is fired. Most browsers expose this under privacy settings; some (Safari, recent Firefox) have removed the global toggle in favor of the GPC option below.
  2. Enable Global Privacy Control (GPC). GPC is a newer, machine-readable opt-out signal recognized by California, Colorado, and Connecticut law as a valid opt-out request. We check for it before initializing PostHog, so a GPC visitor never sets the analytics cookie or fires a single event. Browsers and extensions with built-in GPC support are listed at globalprivacycontrol.org.
  3. Block first-party cookies for simpletexttospeech.io. All major browsers let you block cookies globally or per site. Blocking the ph_*_posthog cookie disables PostHog visitor stitching; the rest of the Service still works without it.

You can also clear cookies, localStorage, sessionStorage, and other site data at any time from your browser settings, or use private / incognito browsing to keep nothing across sessions. The dismissible cookie notice at the bottom of the page is a disclosure, not a consent gate; clicking "Got it" only hides the notice and does not change what we collect. The opt-out paths above are the actual control.

7. Changes to This Policy

If we start using additional cookies or similar technologies, we will update this policy and implement appropriate consent mechanisms as required by law. The "Last updated" date at the top of this page indicates when it was last revised.

Past versions of this policy remain accessible from the "Past versions" block at the bottom of this page so you can see what was in effect on a given date. The same archive treatment is applied to our Terms of Service and Privacy Policy.
