Data Controller and Owner
Everapi GmbH
Getreidegasse 22
A-2284 Untersiebenbrunn, Austria
Commercial register: FN569823a
Managing director: Dominik Kukacka
Email: office@everapi.com
What Data We Collect
We may collect the following types of personal data, either directly or via third parties:
- First name, last name and email address (your account and the contact form)
- Company and billing details (paid plans)
- API usage data: the requests made with your API key, including the request URL, the IP address they came from and the user agent
- Usage data of this website: pages visited, browser, device type and approximate location, collected without cookies
- Postal codes, place names and coordinates you look up (these usually do not identify you)
Each category of data collected is described in detail in the appropriate section of this privacy policy or where specifically explained before data is gathered.
Users may voluntarily provide this data, while usage data is typically collected automatically when interacting with the site.
Unless otherwise noted, all requested data is necessary for proper functionality. If users fail to provide such data, we may not be able to offer our services effectively.
Where optional data is indicated, users can choose not to provide it without affecting service quality.
If unsure about what information is required, users are encouraged to contact the Owner directly.
This website does not use cookies for analytics or advertising. The free tools set one cookie that is strictly necessary for them (see “Free tools” below). The dashboard uses cookies to keep you signed in and for analytics.
Users are solely responsible for any third-party personal data shared through this Application.
How and Where Data Is Processed
Processing Methods
We implement suitable technical and organizational measures to prevent unauthorized access, alteration, disclosure, or destruction of personal data.
Data is processed using IT systems according to procedures closely aligned with stated purposes. Authorized personnel (such as staff in administration, marketing, legal, system operations) or the service providers listed below may access data when needed. They process personal data on our behalf.
Processing Location
Our servers are in Germany. Requests reach them through Cloudflare, and some of the service providers listed below are based in the United States, so data can be transferred outside the EU. See the relevant section of this document for more.
Data Retention
Unless otherwise stated, data is retained only as long as required for the purpose it was collected. We may keep it longer if required by law or with user consent.
Why We Process Data
We collect personal data for the following reasons:
- To deliver and maintain our postal code API
- To comply with legal obligations
- To respond to legal or regulatory requests
- To defend our rights and those of our users or third parties
- To detect and prevent misuse or fraud
- To improve our location data and service quality
- To understand how this website is used, with cookieless analytics
Examples of Processing
1. Contacting Users
When you send the contact form, we receive the data you entered, such as your name, email address, company and message, and use it to answer your inquiry. Cloudflare checks the form for bots (Turnstile) and delivers it to us by email.
2. Hosting, Infrastructure and Service Providers
We use these service providers to host and deliver this Application and its features, to understand how it is used and to take payments. They process personal data on our behalf.
Cloudflare, Inc.
Hosting of this website, its documentation and the free tools (Cloudflare Workers). DNS, network proxy and encryption (TLS) for the API and the dashboard, so every request to them passes through Cloudflare. Bot protection for the contact form and the free tools (Cloudflare Turnstile), delivery of contact form messages by email, and file storage.
Location: United States, global network – Refer to their Privacy Policy for details.
Hetzner Online GmbH
Servers for the API, the dashboard and our databases.
Location: Germany – Refer to their Privacy Policy for details.
PostHog Inc.
Cookieless analytics for this website: which pages are visited, clicks, the referring page, browser, device type, approximate location and page performance. PostHog sets no cookies and stores nothing in your browser. To count unique visitors, it derives a hash from your IP address and browser that changes every day. Email addresses, phone and VAT numbers and IP addresses are removed from page addresses and clicked text before an event is sent. In the dashboard (app.zipcodestack.com), PostHog also links events to your account and records sessions.
Location: EU – Refer to their Privacy Policy for details.
Stripe
Payments and invoices for paid plans. Stripe receives your billing details and payment information; we do not store card numbers.
Location: Ireland, United States – Refer to their Privacy Policy for details.
3. Free Tools
The free tools on this website send what you enter to our API through our Cloudflare Worker, which uses our own API key:
- Before the first lookup, an invisible Cloudflare Turnstile check makes sure you are not a bot. When it passes, the tools set a cookie that is valid for two hours and only proves that the check passed
- Your IP address is used to limit how many lookups a visitor can make
- Cloudflare caches each lookup, together with its result, for up to 30 days, so repeated lookups do not reach the API
- Cloudflare keeps logs of a sample of requests to this website, including tool lookups, for up to 7 days
4. Postal Code Lookup Service
- We process the postal codes, place names and coordinates you send to answer the lookup
- Our own database on our servers in Germany answers the lookups. Requests reach them through Cloudflare
- Requests made with an API key are logged with the request URL, the IP address the request came from and its user agent. We use the log to count requests against your plan, show your usage in the dashboard and prevent abuse
- We do not sell the lookups you make. We share them only with service providers that process data on our behalf, such as Cloudflare
Legal Basis for Processing
We may process personal data when:
- Users have given explicit consent
- Data is required for a contract or pre-contractual arrangements
- Legal obligations demand it
- It serves the public interest or official authority
- We have legitimate business interests that don’t override user rights, such as cookieless analytics of this website and protecting it from bots and abuse
For help determining the legal basis, please contact the Owner.
More on Data Retention
- Data linked to contracts is kept until the agreement is fulfilled
- Data processed under legitimate interest is stored as long as necessary
- If consent was given, data is kept until consent is withdrawn
- Legal obligations may require longer retention
- Lookups made with the free tools are cached at Cloudflare as described under “Free tools”
Once the retention period ends, data is deleted and access/portability rights no longer apply.
GDPR Rights for Users
Under the GDPR, users have the right to:
- Withdraw previously given consent
- Object to data processing for specific reasons
- Request access to their data
- Verify or correct their data
- Restrict processing
- Have data deleted
- Receive data and transfer it to another provider
- File complaints with a data protection authority
Users can also inquire about how data is protected when transferred abroad.
Objecting to Data Processing
If we process data under public interest or legitimate interest, users may object by explaining their specific situation.
Users may always object to direct marketing use without giving a reason. If objected, data will no longer be used for that purpose.
How to Use These Rights
To exercise these rights, users can contact the Owner using the contact details above. Requests are free and will be processed within a month.
If personal data has been shared with others, the Owner will attempt to notify them of any corrections or deletions, unless it’s impossible or overly difficult.
