Slice zucchini into thin rounds. Bring a pot of salted water to a boil over high heat, add zucchini, and cook until tender but firm, about 1 minute. Drain zucchini and rinse under cold water.
Mix together clove garlic, cinnamon, paprika, lemon juice, white vinegar, and olive oil in a bowl. Season with salt and freshly ground black pepper. Mix in zucchini. Serve at room temperature.
