Halloween 2026 contest rules

Who can take part, how to enter, how we choose the winners, the prizes and how we handle your car photo in the Halloween contest on Instagram.

These rules apply to the Halloween 2026 contest on Instagram. By publishing a contest post you accept them.

Organiser

The contest is organised by SEVEN Works s.r.o., Na Vantrokách 42/8, 400 01 Ústí nad Labem, Czech Republic, company ID 23148217 ("we"). We answer questions about the contest at info@sevenworks.cz and in messages on Instagram @seven_works_.

When the contest runs

The contest starts on Thursday 29 October 2026, when we publish the contest page sevenworks.cz/halloween, and ends on Sunday 1 November 2026 at 23:59. We will announce the winners on Tuesday 3 November 2026.

Who can take part

  • Anyone aged 18 or over with a public Instagram account.
  • Taking part is free. You do not have to buy anything.

How to take part

  1. On the page sevenworks.cz/halloween, upload a photo of a car. The photo must be your own or you must have the rights to it, and the car must be yours or one you use. There must be no children in the photo. Iris repaints any adults in it as comic-book figures. It redraws faces in comic style, but clothing, build and pose stay similar to the photo. We discard a picture in which a face looks real.
  2. Choose how the picture should look (scene, mood, car costume and creatures). Iris, our artificial intelligence, repaints the car in the photo as a Halloween picture in comic-book style. The picture will carry the SEVEN Works logo with the address sevenworks.cz/halloween. What happens to the photo along the way is described below under Photo and personal data.
  3. Download the picture and publish it as a post on your Instagram account. When publishing, invite the @seven_works_ account to collaborate. We accept invitations as they come in.
  4. The post must be published no later than Sunday 1 November 2026 at 23:59 and stay published until the winners are announced.

On one device you can create at most 3 pictures for the whole contest. Only a finished picture counts. A photo rejected because of a child, a picture that fails the check and an attempt made while the production queue is full do not count.

Each Instagram account takes part with one post. If you publish more than one, the one with more likes counts. If you cancel the collaboration or delete the post before the winners are announced, the post is not in the contest.

How we choose the winners

  • The 5 contest posts with the most likes on Sunday 1 November 2026 at 23:59 win. We take the number of likes from Instagram.
  • If two posts have the same number of likes, the one published earlier ranks higher.
  • We may exclude a post from the contest if it breaks these rules or Instagram's rules, if it has bought likes or likes from fake accounts, or if it is offensive or otherwise inappropriate. The next post in the ranking then takes its place.
  • We will broadcast the evaluation live on our Instagram @seven_works_ on Tuesday 3 November 2026. In it we will show up to ten contest posts with the most likes, the names of their accounts and their numbers of likes on Sunday 1 November 2026 at 23:59 according to a screen recording made at that moment. A jury from the SEVEN Works studio will check that the posts meet these rules.

Prizes

  • 1st place: detailing of your car worth up to 10,000 CZK. We decide the level of detailing according to the condition of the paint. The prize covers the price in our price list, including surcharges (for example for dark or soft paint), up to 10,000 CZK. You pay anything above that amount. Example: basic detailing of a small or medium car whose paint has only fine marks costs 8,490 CZK in the price list, so the prize covers all of it without surcharges. For a large car or SUV it costs 10,890 CZK and you pay 890 CZK.
  • 2nd place: free tinting of the rear windows. In the price list it costs 2,990 to 7,290 CZK depending on the type of car. If there is old film on the glass, the prize also covers removing it at price-list rates, up to 10,000 CZK in total. You pay anything above that amount.
  • 3rd and 4th place: a 30 % and a 20 % discount on the price-list price of one service of your choice. The discount is at most 10,000 CZK.
  • 5th place: free hand wash of the car's exterior. In the price list it costs 1,390 CZK, or 1,690 CZK for an SUV, MPV, van or pick-up.

You order your prize at our studio in Ústí nad Labem by 31 December 2026 and we agree the date together. The work itself can take place later. Prizes cannot be transferred to another person or exchanged for money, and they cannot be combined with any other discount.

Announcement and handing over the prize

  • We will announce the winners on Tuesday 3 November 2026 in a live broadcast, a post and stories on our Instagram @seven_works_. We will name their Instagram accounts and may show their contest pictures.
  • On the same day we will send each winner a message on Instagram.
  • If a winner does not reply within 7 days of the message, that is by 10 November 2026, the prize lapses.

10 % voucher for participants

Everyone who meets both conditions gets a 10 % discount voucher (the same conditions of entry apply as for the contest):

  1. they fill in the Send me a voucher form on the contest page (e-mail and Instagram account; the form is in Czech), and
  2. from that account they publish a contest post in collaboration with @seven_works_ by Sunday 1 November 2026 at 23:59.
  • We will send the voucher by e-mail with a QR code no later than Wednesday 4 November 2026.
  • It applies to one job at our studio that you order by 31 December 2026. The work itself can take place later. The discount is 10 % of the price-list price of the job, with no upper limit. Show us or tell us the code from the e-mail when you order and we will enter the discount in the quote.
  • There is one voucher per Instagram account and per e-mail address, and it can be redeemed once.
  • The voucher discount and a contest prize cannot be combined: the voucher cannot be used for a job for which you redeem a prize. The voucher cannot be combined with any other discount either.

Data from the form. We use the e-mail address and Instagram account from the form to check the collaboration and send you the voucher (Article 6(1)(b) GDPR). The e-mail with the voucher is sent through the Google Workspace service. We keep the data from the form for 24 months after the end of the contest and then delete them. If you consented to news, we keep your e-mail address for that purpose until you withdraw your consent. We will send you news and offers by e-mail only if you tick the separate consent box in the form. You can unsubscribe at any time using the link in each such e-mail.

Photo and personal data

The photo for editing. The photo is sent only after you give your consent on the contest page. We process it as follows:

  1. We reduce the photo in size and remove location and device data (EXIF and GPS) from it.
  2. Artificial intelligence from Anthropic (the Claude model) checks whether there is a child in the photo. Anthropic receives the photo with faces in it. It recognises a child only by appearance and does not find out who is in the photo. We reject a photo that might show a child and do not send it anywhere else. Processing at Anthropic may also take place outside the European Economic Area, including in the USA.
  3. We blur the registration plate in the photo.
  4. Artificial intelligence from Google (the Vertex AI service) repaints the car in the photo as a Halloween picture. It also repaints any adults in the photo as comic-book figures. We do not blur faces beforehand, so Google receives the photo with them. Processing takes place in a data centre in the EU.
  5. Anthropic checks the finished picture again. We do not send a picture that fails the check. It fails, for example, if a face in it looks real, if it shows a child figure or if a registration plate is legible. Such a picture does not count as an attempt. We send you any other picture on the page. Your browser adds the SEVEN Works logo to it.

We do not store the uploaded photo. It is processed in memory only and discarded once the edit is finished. The record of the service call keeps only technical data (task, model, duration, cost and a one-way fingerprint from which the photo cannot be recovered). We edit the photo on the basis of your consent (Article 6(1)(a) GDPR). The consent covers that one edit only. If other people appear in the photo, we process their likeness in memory only, so that Anthropic can check that no child is in it and Google can repaint them, and we discard it once the edit is finished. We do this on the basis of our legitimate interest in running the contest (Article 6(1)(f) GDPR).

The finished picture. We store the finished picture for our internal analysis of the contest (for example which scenes and costumes people choose). With it we store only the options chosen, the time, the model used and the result of the check. We do not store your e-mail address, IP address or device fingerprint with it. Only a picture that has passed the check that no face in it looks real and that it shows no child figure and no legible registration plate is stored. We will not publish it, and only the website administrator has access to it. We delete it by 31 December 2026 at the latest. We do this on the basis of our legitimate interest in evaluating the contest (Article 6(1)(f) GDPR).

Number of attempts. To make sure no more than 3 pictures are created on one device, the site stores a technical cookie with a random identifier in your browser (valid for 7 days). For the attempts we store only a one-way fingerprint of this identifier and of your IP address, the attempt number and result and the time, without the photo. We delete these records 30 days after the end of the contest. The IP address itself is kept only temporarily in the server's memory for the limits. We do this on the basis of our legitimate interest in a fair contest and in preventing abuse (Article 6(1)(f) GDPR).

The contest on Instagram. You publish the post yourself on Instagram, which is operated by Meta Platforms Ireland Limited under its own terms and policies. For the contest we process the name of your Instagram account, your contest post and its number of likes. For winners also the messages you exchange with us and the details we need to hand over the prize: name, phone or e-mail and what car you have. We process them to evaluate the contest, announce the winners and hand over the prizes under these rules (Article 6(1)(b) GDPR). We keep them for 24 months after the end of the contest and then delete them.

Through the collaboration your post also appears on our profile. In the announcement we will name the winners' accounts and may show their contest pictures. In the live evaluation we will also show other posts in the top ten by likes and the names of their accounts.

What rights you have and how to exercise them is described on the page Personal Data Processing.

Instagram

The contest is in no way sponsored, endorsed or administered by, or associated with, Instagram or Meta. Neither Instagram nor Meta is responsible for the contest. Please send questions about the contest to us, not to Instagram.

Changes to the rules

We may change the rules only for a serious reason, for example if Instagram changes its terms or if photo editing stops working. We will publish any change on this page with its date. A change must not make the conditions worse for posts that are already in the contest.

Change of 30 October 2026: adults may now appear in the photo, and Iris repaints them as comic-book figures. We still reject photos with children.
