Privacy & Data Policy
A clear, transparent disclosure of how oTimers protects your digital privacy. We operate on a zero-collection, client-side architecture: no accounts, no tracking cookies, and zero advertising pixels.
Zero Personal Data Collection by Design
We cannot sell, share, leak, or lose your personal data because we never collect it. Privacy is not a feature we toggle on—it is the foundational architecture of the platform:
No passwords, email addresses, or account databases to hack, breach, or compromise.
All calculations run in your device's browser memory via requestAnimationFrame. Nothing is sent to our servers.
No Google Analytics, Meta Pixels, programmatic ad trackers, or third-party profiling scripts.
We do not monetize your attention, sell telemetry, or partner with behavioral advertising networks.
How Our Client-Side Model Protects You
Traditional web utilities pass your actions through remote servers to build behavioral ad profiles. Here is how oTimers works differently.
Static Edge Delivery
Static HTML, CSS, and minimal vanilla JavaScript are served over TLS 1.3 encrypted HTTPS via high-speed edge distribution.
In-Browser Math
Countdowns, interval sweeps, and stopwatch ticks calculate locally using your device’s internal high-precision clock (performance.now()).
Procedural Audio Synthesis
Sound alerts are generated mathematically using the native Web Audio API directly in your browser, rather than streaming external audio files.
Transient Local Memory
Input fields (such as quiz buzzer teams or custom interval timers) reside in ephemeral RAM. Refreshing the browser tab purges all active states.
LocalStorage Transparency Disclosure
We do not use tracking cookies. The only data saved to your device is stored in your browser's standard localStorage to remember your display preferences across visits.
| Key Name | Purpose | Storage Type | Where Stored |
|---|---|---|---|
otimers-theme | Remembers your interface theme preference ("dark" or "light"). | localStorage | Device only |
otimers-face | Saves your preferred clock face design (e.g. "midnight", "classic"). | localStorage | Device only |
otimers-custom-theme | Stores your custom hex accent color if customized in the settings drawer. | localStorage | Device only |
You can purge all oTimers preference keys from your browser at any time with one click.
Compliance with Global Privacy Statutes
Because oTimers does not collect personal data, we meet global data privacy frameworks by default.
General Data Protection Regulation
Under GDPR Article 5 (Data Minimization), digital services must limit data collection to what is necessary. oTimers practices absolute minimization: zero personal data is collected or processed. Your right to erasure (Article 17) is continuously satisfied because no records exist on our servers.
California Consumer Privacy Act
oTimers does not "sell" or "share" consumer personal information as defined under the CCPA/CPRA, because no personal information is ever harvested. No opt-out links or "Do Not Sell My Info" waivers are needed because zero data commerce occurs.
Student & Child Privacy Standards
oTimers is 100% compliant with US federal student privacy laws including COPPA, FERPA, and CIPA. We never collect data from children under 13, nor do we handle student education records. Read our full Classroom Compliance Charter →
Edge Server Access Logs
When you visit oTimers, our edge network infrastructure (such as standard CDN routing) temporarily logs technical connection metadata (such as IP address and browser user-agent) solely to deliver packets, defend against DDoS attacks, and maintain uptime. These ephemeral network logs are never linked to personal identities.
Frequently Asked Questions About Privacy
Do you use cookies or tracking pixels?
No. oTimers does not set any tracking cookies, marketing cookies, or third-party advertising pixels. We do not use Google Analytics, Meta Pixels, or session replay scripts.
Can oTimers see what I am timing or what labels I type?
No. All countdown timers, stopwatch splits, meeting rates, custom labels, and team names run strictly in your device’s local browser memory (RAM). Zero timing data is ever transmitted to our servers.
Do you sell or monetize personal information?
No. We cannot sell, rent, or trade your personal information because we never collect it in the first place. We do not partner with data brokers or ad networks.
How does oTimers comply with GDPR and CCPA without a cookie banner?
Cookie consent banners and "Do Not Sell My Info" links are legally mandated when a website tracks users across sites or processes personal data. Because oTimers collects zero personal data and uses zero tracking cookies, privacy is preserved by default without intrusive popups.
How can I completely delete my local data?
All preferences reside solely in your browser’s local storage on your machine. You can clear them anytime using the "Clear Local Storage Settings" button on this page or through your browser’s standard "Clear Site Data" menu.
